[5][6] This gene encodes a member of the Rho-GAP family of GTPase activating proteins.

The protein has substantial GAP activity towards several Rho-family GTPases in vitro, converting them to an inactive GDP-bound state.

It is implicated in regulating adhesion of hematopoietic cells to the extracellular matrix.

Multiple transcript variants encoding different isoforms have been found for this gene.
