Also known as ARHGAP3RhoGAP3
Summary
CHN2 (chimerin 2, HGNC:1944) is a protein-coding gene on chromosome 7p14.3, encoding Beta-chimaerin (P52757). GTPase-activating protein for p21-rac.
This gene encodes a guanosine triphosphate (GTP)-metabolizing protein that contains a phorbol-ester/diacylglycerol (DAG)-type zinc finger, a Rho-GAP domain, and an SH2 domain. The encoded protein translocates from the cytosol to the Golgi apparatus membrane upon binding by diacylglycerol (DAG). Activity of this protein is important in cell proliferation and migration, and expression changes in this gene have been detected in cancers. A mutation in this gene has also been associated with schizophrenia in men. Alternative transcript splicing and the use of alternative promoters results in multiple transcript variants.

Function. 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 location. Membrane.
Tissue specificity. 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.
Activity regulation. In the inactive state, the N terminus protrudes into the active site of the Rho-GAP domain, sterically blocking Rac binding. Phospholipid binding to the Phorbol-ester/DAG-type zinc-finger/C1 domain triggers the cooperative dissociation of these interactions, allowing the N-terminus to move out of the active site and thereby activating the enzyme.
