There is a very high volume of traffic coming from your site (IP address as of Thu Oct 28 02:46:08 2021 (California time). So that other users get a fair share of our bandwidth, we are putting in a delay of 13.9 seconds before we service your request. This delay will slowly decrease over a half hour as activity returns to normal. This high volume of traffic is likely due to program-driven rather than interactive access, or the submission of queries on a large number of sequences. If you are making large batch queries, please write to our public mailing list and inquire about more efficient ways to access our data. If you are sharing an IP address with someone who is submitting large batch queries, we apologize for the inconvenience.

DESCRIPTION: RecName: Full=Nascent polypeptide-associated complex subunit alpha; Short=NAC-alpha; AltName: Full=Alpha-NAC; AltName: Full=GAL4 DNA-binding enhancer protein 2;
FUNCTION: Component of the nascent polypeptide-associated complex (NAC), a dynamic component of the ribosomal exit tunnel, protecting the emerging polypeptides from interaction with other cytoplasmic proteins to ensure appropriate nascent protein targeting. The NAC complex also promotes mitochondrial protein import by enhancing productive ribosome interactions with the outer mitochondrial membrane and blocks the inappropriate interaction of ribosomes translating non-secretory nascent polypeptides with translocation sites in the membrane of the endoplasmic reticulum. EGD2 is also involved in transcription regulation.
SUBUNIT: Part of the nascent polypeptide-associated complex (NAC), consisting of EGD2 and either EGD1 or BTT1. NAC associates with ribosomes via EGD1 or BTT1, and with the CCR4-NOT complex.
INTERACTION: Q02642:EGD1; NbExp=4; IntAct=EBI-6379, EBI-6371; P15731:UBC4; NbExp=2; IntAct=EBI-6379, EBI-19735;
SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Predominantly cytoplasmic, may also transiently localize to the nucleus. Nuclear import may occur via redundant pathways including one requiring the karyopherins PSE1 and KAP123, which also participate in nuclear import of ribosomal subunits.
DOMAIN: The UBA domain is required for the stability of EGD1.
PTM: Ubiquitinated by the NOT4 E3 ligase and the UBC4 E2 ubiquitin conjugatin enzyme.
MISCELLANEOUS: Present with 38016 molecules/cell in log phase SD medium.
SIMILARITY: Belongs to the NAC-alpha family.
SIMILARITY: Contains 1 NAC-A/B (NAC-alpha/beta) domain.
SIMILARITY: Contains 1 UBA domain.

ModBase Predicted Comparative 3D Structure on P38879
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
