Acts as a GTPase-activating protein for RAB7A. Signal effector acting as a linker between RAC1 and RAB7A, leading to RAB7A inactivation and subsequent inhibition of cadherin degradation and reduced cell-cell adhesion.
Subcellular locations: Cytoplasm, Cytoplasmic vesicle, Cell junction
Expressed in a broad range of tissues, especially in kidney, liver, lung and placenta. Also expressed in keratinocytes and epithelia-containing organs. Isoform 2 is differentially expressed in prostate normal and cancer cells (at protein level).
