研究背景

機能:

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.

組織特異性:

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

タンパク質ファミリー:

The DH domain is involved in interaction with CCPG1.
