ID:SLAP1_HUMAN DESCRIPTION: RecName: Full=Src-like-adapter; AltName: Full=Src-like-adapter protein 1; Short=SLAP-1; Short=hSLAP; FUNCTION: Adapter protein, which negatively regulates T-cell receptor (TCR) signaling. Inhibits T-cell antigen-receptor induced activation of nuclear factor of activated T-cells. Involved in the negative regulation of positive selection and mitosis of T-cells. May act by linking signaling proteins such as ZAP70 with CBL, leading to a CBL dependent degradation of signaling proteins. SUBUNIT: Interacts with EPHA2, VAV1, LCP2 and PDGFRB (By similarity). Homodimer. Homodimerization and interaction with phosphorylated CBL occurs via its C-terminal domain. Interacts with phosphorylated proteins ZAP70, CD3Z, SYK and LAT via its SH2 domain. SUBCELLULAR LOCATION: Cytoplasm (By similarity). Endosome (By similarity). Note=Colocalizes with endosomes (By similarity). TISSUE SPECIFICITY: Expressed in lung and fetal brain. Weakly expressed in heart, adult brain, placenta, liver, skeletal muscle, kidney and pancreas. INDUCTION: By all-trans retinoic acid (ATRA). Induction is indirect and is mediated through other proteins. DOMAIN: The C-terminal domain is essential for the homodimerization and the interaction with CBL. While the interaction with CBL is apparently mediated via the hydrophobic region of this domain, the highly charged region is apparently required for the homodimerization. SIMILARITY: Contains 1 SH2 domain. SIMILARITY: Contains 1 SH3 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.
