Background: Heterotrimeric G proteins are essential cellular signal transducers. Members (Gαq, Gα11, Gα14, Gα15 and Gα16) of the Gq sub-family of G proteins are known to stimulate phospholipase C. Other biochemical and physiological functions of Gαq sub-family are being explored.
Immunogen: A synthetic peptide common to all members of Gαq subfamily.
