Biochem/physiol Actions

FGR interacts with Fc?RII and thus, regulates Fc?RII-mediated signaling cascade.
This protein is expressed in B-cells of patients with Epstein-Barr virus-associated lymphoproliferative disease and chronic lymphocytic leukemia. It is also expressed in normal mantle zone B-cells and is controlled developmentally during the differentiation of myelomonocytes.

General description

Src family of tyrosine kinases is grouped into two classes- those with wide range of expression, and those with narrow range of tissue expression. Fgr belongs to the latter group. This protein has six functional domains namely, Src homology domain 4 (SH4), a unique domain, SH3 domain, SH2 domain, the catalytic SH1 domain, and a regulatory region in C-terminal. It is expressed in natural killer cells, monocytes and granulocytes.
