Normally, G proteins are regulated by GAP, which results in controlled cell division.
G proteins have an inherent GTPase hydrolytic activity that is slow. However, in the presence of GAP, this hydrolytic activity is fast.
Without GAP, G proteins are constitutively on because of their slow hydrolytic activity and GEFs constantly replacing GDP with GTP. This results in unregulated cell division and the formation of tumors.
G proteins without hydrolytic activity cannot hydrolyze bound GTP. GAPs cannot activate a nonfunctional enzyme, and the G protein is constitutively active, resulting in unregulated cell division and the formation of tumors.
