CC -!- FUNCTION: Contains a GTPase activator for the Rho-type GTPases (RhoGAP)
CC domain that would be able to negatively regulate the actin cytoskeleton
CC as well as cell spreading. However, also contains N-terminally a BAR-
CC domin which is able to play an autoinhibitory effect on this RhoGAP
CC activity. {ECO:0000250|UniProtKB:Q92619}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q92619}. Cell
CC projection, ruffle membrane {ECO:0000250|UniProtKB:Q92619}.
CC -!- DOMAIN: Rho-GAP domain is able to regulate RhoGTPase activity, actin
CC cytoskeleton and cell spreading. However N-terminally BAR domain plays
CC an autoinhibitory role. {ECO:0000250|UniProtKB:Q92619}.
