Research Backgrounds

Function:

Couples tyrosine kinase signals with the activation of the Rho/Rac GTPases, thus leading to cell differentiation and/or proliferation.

PTMs:

Phosphorylated on tyrosine residues by HCK in response to IFNG and bacterial lipopolysaccharide (LPS) (By similarity). Phosphorylated by FYN.

Tissue Specificity:

Widely expressed in hematopoietic cells but not in other cell types.

Subunit Structure:

Interacts with SHB. Interacts with APS, GRB2, GRB3, DOCK2, SLA, TEC and ZNF655/VIK. Interacts with SIAH2; without leading to its degradation. Associates with BLNK, PLCG1, GRB2 and NCK1 in a B-cell antigen receptor-dependent fashion. Interacts with CBLB; which inhibits tyrosine phosphorylation and down-regulates activity. May interact with CCPG1. Interacts with CLNK. Interacts with THEMIS2 (By similarity). Interacts with NEK3 and this interaction is prolactin-dependent. Interacts with ITK. Interacts with PTK2B/PYK2 (By similarity). Interacts with HCK. Interacts with PTK2B/PYK2. Interacts (via SH2 domain) with SYK. Interacts with ANKRD54. Interacts with CD6 (By similarity).

Family&Domains:

The DH domain is involved in interaction with CCPG1.
