Gai2 is a 40-41kD alpha-subunit of heterotrimeric protein that shares sequence homology with Gai3 and Gai1. All these G proteins can be ADP-ribosylated at the carboxy terminal Cys of the CAAX sequence, interfering with receptor coupling. Gai2 is expressed widely in tissues and cell lines. Activation of PLC-b by Gai-coupled receptors is the result of release of Gbg subunits from Gai. Gai2 regulates potassium channel activation. Mutation at Arg179 has been identified in tumors. This and the Q205L mutant inhibit adenylyl cyclase.

Suitable for use in FLISA and Western Blot. Other applications not tested.

Optimal dilutions to be determined by the researcher.
