Based on previous mapping of the G beta gamma binding region of beta ARK , and conserved residues within the PH domain , we have constructed a series of mutants in the carboxyl terminus of beta ARK in order to determine important residues involved in G beta gamma and PIP2 binding .
 G beta gamma binding region, beta ARK, PH domain, beta ARK, G beta gamma
