General annotation (Comments)

Function

GTPase activator for the Rho-type GTPases by converting them to an inactive GDP-bound state. Has a substantial GAP activity toward CDC42 and RAC1 and less toward RHOA. Has a role in regulating adhesion of hematopoietic cells to the extracellular matrix.

Tissue specificity

Predominantly expressed in peripheral blood leukocytes, spleen, and thymus.

Sequence similarities

Contains 1 PH domain.

Contains 1 Rho-GAP domain.

Contains 1 SH3 domain.

Contains 1 WW domain.
