Summaries for CHN2 Gene

Entrez Gene Summary for CHN2 Gene

  • 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.

GeneCards Summary for CHN2 Gene

CHN2 (Chimerin 2) is a Protein Coding gene. Diseases associated with CHN2 include schizophrenia. Among its related pathways are RhoGDI Pathway and Signaling by GPCR. GO annotations related to this gene include GTPase activator activity and SH3/SH2 adaptor activity. An important paralog of this gene is CHN1.

UniProtKB/Swiss-Prot for CHN2 Gene

  • 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

Function for CHN2 Gene

Molecular function for CHN2 Gene

GENATLAS Biochemistry: chimerin beta-2,GTPase activating protein for the ras-related p21rac,DAG (diacylglycerol) receptor,expressed in cerebellum,homolog to CHN1
UniProtKB/Swiss-Prot EnzymeRegulation: 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.
UniProtKB/Swiss-Prot 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
