GTPase-activating protein for p21-rac. Insufficient expression of beta-2 chimaerin is expected to lead to higher Rac activity and could therefore play a role in the progression from low-grade to high-grade tumors.
Subcellular locations: Membrane
Highest levels in the brain and pancreas. Also expressed in the heart, placenta, and weakly in the kidney and liver. Expression is much reduced in the malignant gliomas, compared to normal brain or low-grade astrocytomas.
