ID:STAM1_HUMAN DESCRIPTION: RecName: Full=Signal transducing adapter molecule 1; Short=STAM-1; FUNCTION: Involved in intracellular signal transduction mediated by cytokines and growth factors. Upon IL-2 and GM-CSL stimulation, it plays a role in signaling leading to DNA synthesis and MYC induction. May also play a role in T-cell development. Involved in down-regulation of receptor tyrosine kinase via multivesicular body (MVBs) when complexed with HGS (ESCRT-0 complex). The ESCRT-0 complex binds ubiquitin and acts as sorting machinery that recognizes ubiquitinated receptors and transfers them to further sequential lysosomal sorting/trafficking processes. SUBUNIT: Component of the ESCRT-0 complex composed of STAM or STAM2 and HGS. Probably part of a complex at least composed of HSG, STAM and EPS15. Interacts with STAMBP/AMSH. Interacts with PDGFRB. INTERACTION: O95630:STAMBP; NbExp=3; IntAct=EBI-752333, EBI-396676; SUBCELLULAR LOCATION: Cytoplasm (Probable). Early endosome membrane; Peripheral membrane protein; Cytoplasmic side (Probable). TISSUE SPECIFICITY: Ubiquitously expressed. PTM: Phosphorylated on Tyr-198. Phosphorylated in response to IL2, IL3, IL4, IL7, CSF2/GM-CSF, EGF and PDGFB. Phosphorylated by activated PDGFRB. SIMILARITY: Belongs to the STAM family. SIMILARITY: Contains 1 ITAM domain. SIMILARITY: Contains 1 SH3 domain. SIMILARITY: Contains 1 UIM (ubiquitin-interacting motif) repeat. SIMILARITY: Contains 1 VHS domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

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.
