| Primary Identifier | IPR035572 | Type | Domain |
| Short Name | Tec_SH3 |
| description | This entry represents the SH3 domain of Tec [, ]. Tec is a cytoplasmic (or nonreceptor) tyrosine kinase containing Src homology protein interaction domains (SH3, SH2) N-terminal to the catalytic tyr kinase domain []. It also contains an N-terminal pleckstrin homology (PH) domain, which binds the products of PI3K and allows membrane recruitment and activation, and the Tec homology (TH) domain, which contains proline-rich and zinc-binding regions []. It is more widely-expressed than other Tec subfamily kinases. Tec is found in endothelial cells, both B- and T-cells, and a variety of myeloid cells including mast cells, erythroid cells, platelets, macrophages and neutrophils [, ]. Tec is a key component of T-cell receptor (TCR) signaling, and is important in TCR-stimulated proliferation and phospholipase C-gamma1 activation []. |
