Human Gene TIAM1 (ENST00000286827.7) from GENCODE V44
  Description: Homo sapiens TIAM Rac1 associated GEF 1 (TIAM1), transcript variant 1, mRNA. (from RefSeq NM_003253)
RefSeq Summary (NM_003253): This gene encodes a RAC1-specific guanine nucleotide exchange factor (GEF). GEFs mediate the exchange of guanosine diphosphate (GDP) for guanosine triphosphate (GTP). The binding of GTP induces a conformational change in RAC1 that allows downstream effectors to bind and transduce a signal. This gene thus regulates RAC1 signaling pathways that affect cell shape, migration, adhesion, growth, survival, and polarity, as well as influencing actin cytoskeletal formation, endocytosis, and membrane trafficking. This gene thus plays an important role in cell invasion, metastasis, and carcinogenesis. In addition to RAC1, the encoded protein activates additional Rho-like GTPases such as CDC42, RAC2, RAC3 and RHOA. This gene encodes multiple protein isoforms that experience a diverse array of intramolecular, protein-protein, and phosphorylation interactions as well as phosphoinositide binding. Both the longer and shorter isoforms have C-terminal Dbl homology (DH) and pleckstrin homology (PH) domains while only the longer isoforms of this gene have the N-terminal myristoylation site and the downstream N-terminal PH domain, ras-binding domain (RBD), and PSD-95/DlgA/ZO-1 (PDZ) domain. [provided by RefSeq, Jul 2017]. Sequence Note: The RefSeq transcript and protein were derived from genomic sequence to make the sequence consistent with the reference genome assembly. The genomic coordinates used for the transcript record were based on alignments.

  ID: TIAM1_HUMAN
DESCRIPTION: RecName: Full=T-lymphoma invasion and metastasis-inducing protein 1; Short=TIAM-1;
FUNCTION: Modulates the activity of RHO-like proteins and connects extracellular signals to cytoskeletal activities. Acts as a GDP- dissociation stimulator protein that stimulates the GDP-GTP exchange activity of RHO-like GTPases and activates them. Activates RAC1, CDC42, and to a lesser extent RHOA.
SUBUNIT: Component of the Par polarity complex, composed of at least phosphorylated PRKCZ, PARD3 and TIAM1. Interacts with NTRK2; mediates the activation of RAC1 by BDNF (By similarity). Interacts with BAIAP2. Interacts with EPHA8; regulates clathrin-mediated endocytosis of EPHA8.
SUBCELLULAR LOCATION: Cell junction. Note=Presence of KRIT1, CDH5 and RAP1B is required for its localization to the cell junction.
TISSUE SPECIFICITY: Found in virtually all analyzed tumor cell lines including B- and T-lymphomas, neuroblastomas, melanomas and carcinomas.
SIMILARITY: Belongs to the TIAM family.
SIMILARITY: Contains 1 DH (DBL-homology) domain.
SIMILARITY: Contains 1 PDZ (DHR) domain.
SIMILARITY: Contains 2 PH domains.
SIMILARITY: Contains 1 RBD (Ras-binding) domain.

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.
