functionText
  • Molecule 'Replicase polyprotein 1ab': Multifunctional protein involved in the transcription and replication of viral RNAs. Contains the proteinases responsible for the cleavages of the polyprotein.
  • Molecule 'Host translation inhibitor nsp1': Inhibits host translation by interacting with binds to the host 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome (PubMed:32680882,PubMed:32908316). The C-terminus binds to and obstructs ribosomal mRNA entry tunnel (PubMed:32680882,PubMed:32908316). Thereby inhibits antiviral response triggered by innate immunity or interferons (PubMed:32680882,PubMed:32979938). The nsp1-40S ribosome complex further induces an endonucleolytic cleavage near the 5'UTR of host mRNAs, targeting them for degradation (By similarity). Viral mRNAs less susceptible to nsp1-mediated inhibition of translation, because of their 5'-end leader sequence (PubMed:32908316). By suppressing host gene expression, nsp1 facilitates efficient viral gene expression in infected cells and evasion from host immune response (By similarity).
  • Molecule 'Non-structural protein 2': May play a role in the modulation of host cell survival signaling pathway by interacting with host PHB and PHB2. Indeed, these two proteins play a role in maintaining the functional integrity of the mitochondria and protecting cells from various stresses.
  • Molecule 'Non-structural protein 3': Responsible for the cleavages located at the N-terminus of the replicase polyprotein. Participates together with nsp4 in the assembly of virally-induced cytoplasmic double-membrane vesicles necessary for viral replication (By similarity). Antagonizes innate immune induction of type I interferon by blocking the phosphorylation, dimerization and subsequent nuclear translocation of host IRF3 (PubMed:32733001). Prevents also host NF-kappa-B signaling (By similarity). In addition, PL-PRO possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates (PubMed:32726803). Cleaves preferentially ISG15 from substrates in vitro (PubMed:32726803). Can play a role in host ADP-ribosylation by binding ADP-ribose (PubMed:32578982).
  • Molecule 'Non-structural protein 4': Participates in the assembly of virally-induced cytoplasmic double-membrane vesicles necessary for viral replication.
  • Molecule '3C-like proteinase': Cleaves the C-terminus of replicase polyprotein at 11 sites (PubMed:32321856). Recognizes substrates containing the core sequence [ILMVF]-Q-|-[SGACN] (PubMed:32198291, PubMed:32272481). Also able to bind an ADP-ribose-1''-phosphate (ADRP) (By similarity) (PubMed:32198291, PubMed:32272481).
  • Molecule 'Non-structural protein 6': Plays a role in the initial induction of autophagosomes from host reticulum endoplasmic (By similarity). Later, limits the expansion of these phagosomes that are no longer able to deliver viral components to lysosomes (By similarity). Binds to host TBK1 without affecting TBK1 phosphorylation; the interaction with TBK1 decreases IRF3 phosphorylation, which leads to reduced IFN-beta production (PubMed:32979938).
  • Molecule 'Non-structural protein 7': Plays a role in viral RNA synthesis (PubMed:32358203, PubMed:32277040, PubMed:32438371, PubMed:32526208). Forms a hexadecamer with nsp8 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers (By similarity).
  • Molecule 'Non-structural protein 8': Plays a role in viral RNA synthesis (PubMed:32358203, PubMed:32277040, PubMed:32438371, PubMed:32526208). Forms a hexadecamer with nsp7 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers (By similarity).
  • Molecule 'Non-structural protein 9': May participate in viral replication by acting as a ssRNA-binding protein.
  • Molecule 'Non-structural protein 10': Plays a pivotal role in viral transcription by stimulating both nsp14 3'-5' exoribonuclease and nsp16 2'-O-methyltransferase activities. Therefore plays an essential role in viral mRNAs cap methylation.
  • Molecule 'RNA-directed RNA polymerase': Responsible for replication and transcription of the viral RNA genome.
  • Molecule 'Helicase': Multi-functional protein with a zinc-binding domain in N-terminus displaying RNA and DNA duplex-unwinding activities with 5' to 3' polarity. Activity of helicase is dependent on magnesium (By similarity). Binds to host TBK1 and inhibits TBK1 phosphorylation; the interaction with TBK1 decreases IRF3 phosphorylation, which leads to reduced IFN-beta production (PubMed:32979938).
  • Molecule 'Proofreading exoribonuclease': Enzyme possessing two different activities: an exoribonuclease activity acting on both ssRNA and dsRNA in a 3' to 5' direction and a N7-guanine methyltransferase activity. Acts as a proofreading exoribonuclease for RNA replication, thereby lowering The sensitivity of the virus to RNA mutagens.
  • Molecule 'Uridylate-specific endoribonuclease': Mn(2+)-dependent, uridylate-specific enzyme, which leaves 2'-3'-cyclic phosphates 5' to the cleaved bond.
  • Molecule '2'-O-methyltransferase': Methyltransferase that mediates mRNA cap 2'-O-ribose methylation to the 5'-cap structure of viral mRNAs. N7-methyl guanosine cap is a prerequisite for binding of nsp16. Therefore plays an essential role in viral mRNAs cap methylation which is essential to evade immune system.

Precurs. Proteins (unipCov2FullSeq) Track Description
 

Description

This track shows protein sequence annotations from the UniProt/SwissProt database, mapped to genomic coordinates. The data has been curated from scientific publications by the UniProt/SwissProt staff. The annotations are spread over multiple tracks, based on their "feature type" in UniProt:

Track Name Description
UCSC Alignment, SwissProt Protein sequences from SwissProt mapped onto the genome. All other tracks are (start,end) annotations mapped using this track.
UCSC Alignment, TrEMBL Protein sequences from TrEMBL mapped onto the genome. All other tracks are (start,end) annotations mapped using this track. This track is hidden by default. To show it, click its checkbox on the track description page.
UniProt Signal Peptides Regions found in proteins destined to be secreted, generally cleaved from mature protein.
UniProt Extracellular Domains Protein domains with the comment "Extracellular".
UniProt Transmembrane Domains Protein domains of the type "Transmembrane".
UniProt Cytoplasmic Domains Protein domains with the comment "Cytoplasmic".
UniProt Polypeptide Chains Polypeptide chain in mature protein after post-processing.
UniProt Domains Protein domains, zinc finger regions and topological domains.
UniProt Disulfide Bonds Disulfide bonds.
UniProt Amino Acid Modifications Glycosylation sites, modified residues and lipid moiety-binding regions.
UniProt Amino Acid Mutations Mutagenesis sites and sequence variants.
UniProt Protein Primary/Secondary Structure Annotations Beta strands, helices, coiled-coil regions and turns.
UniProt Sequence Conflicts Differences between Genbank sequences and the UniProt sequence.
UniProt Repeats Regions of repeated sequence motifs or repeated domains.
UniProt Other Annotations All other annotations

Display Conventions and Configuration

Genomic locations of UniProt/SwissProt annotations are labeled with a short name for the type of annotation (e.g. "glyco", "disulf bond", "Signal peptide" etc.). A click on them shows the full annotation and provides a link to the UniProt/SwissProt record for more details. TrEMBL annotations are always shown in light blue, except in the Signal Peptides, Extracellular Domains, Transmembrane Domains, and Cytoplamsic domains subtracks.

Mouse-over a feature to see the full UniProt annotation comment. For variants, the mouse-over will show the full name of the UniProt disease acronym.

The subtracks for domains related to subcellular location are sorted from outside to inside of the cell: Signal peptide, extracellular, transmembrane, and cytoplasmic.

In the "UniProt Modifications" track, lipoification sites are highlighted in dark blue, glycosylation sites in dark green, and phosphorylation in light green.

Methods

UniProt sequences were aligned to UCSC/Gencode transcript sequences first with BLAT, filtered with pslReps (93% query coverage, within top 1% score), lifted to genome positions with pslMap and filtered again. UniProt annotations were obtained from the UniProt XML file. The annotations were then mapped to the genome through the alignment using the pslMap program. This mapping approach draws heavily on the LS-SNP pipeline by Mark Diekhans. Like all Genome Browser source code, the main script used to build this track can be found on GitHub.

Data Access

The raw data can be explored interactively with the Table Browser or the Data Integrator. For automated analysis, the genome annotation is stored in a bigBed file that can be downloaded from the download server. The exact filenames can be found in the track configuration file. Annotations can be converted to ASCII text by our tool bigBedToBed which can be compiled from the source code or downloaded as a precompiled binary for your system. Instructions for downloading source code and binaries can be found here. The tool can also be used to obtain only features within a given range, for example:
