LIG_TYR_ITAM - ITAM (immunoreceptor tyrosine-based activatory motif). ITAM consists of partially conserved short sequence of amino acid found in the cytoplasmatic tail of antigen and Fc receptors. | |||||||
| CD3E_HUMAN | 185 | 202 | Specificity | Altered binding specificity | Phosphorylation of T-cell surface glycoprotein CD3 epsilon chain (CD3E) by Lck (Tyrosine-protein kinase Lck (LCK)) during T cell activation switches the specificity of CD3E from SH3 domain containing proteins like Epidermal growth factor receptor kinase substrate 8-like protein 1 (EPS8L1) to SH2 domain containing proteins like Tyrosine-protein kinase ZAP-70 (ZAP70). | ||
