Background/aim: Rho small GTPases regulate cancer cell adhesion, migration and invasion through reorganization of the actin cytoskeleton. Rho GTPase Activating Protein 22 (ARHGAP22) is a Rac-specific GAP and suppresses Rac-dependent lamella formation and cell spreading. We have previously shown that ARHGAP22 localizes at endosomes in human melanoma A7 cells.

We have previously shown that FilGAP, a Rac-specific GAP, binds to the actin-cross-linking protein Filamin A (FLNa) and suppresses Rac-dependent lamellae formation and cell spreading. ARHGAP22 is a member of FilGAP family, and implicated in the regulation of tumor cell motility.
