General description

CHN1 is a 38-kDa GTPase-activating protein (GAP) and phorbol ester receptor domain. α-chimaerin gene have two isoforms, α1and α2 chimaerin. Both the isoforms contain C1 and Rho-GAP domains but α2 isoform contains an N-terminal SH2 domain which is absent in α1. It has N-terminal SH2 domain, the C-terminal RhoGAP domain and the central C1 domain similar to protein kinase C.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Anti-CHN1 (151-165) antibody is suitable for western blot at a dilution of 1:500-1:2,000.

Biochem/physiol Actions

α1-chimaerin is expressed in developing neurons and is controlled by synaptic activity. It plays a crucial role in human neuronal signal-transduction mechanisms. Any alteration in α1-chimaerin expression leads to the pruning of dendritic spines and branches and supression of its expression leads to increased process growth from the dendritic shaft and from spine heads.
