G12/G13 subunits are alpha units of heterotrimeric G proteins that regulate cell processes through the use of guanine nucleotide exchange factors.[1] These two subunits represent a fourth class of G protein alpha subunits.[2] They are not sensitive to pertussis toxin.[3]
G proteins G12 and G13 regulate actin cytoskeletal remodeling in cells.[4] G13 is also essential for receptor tyrosine kinase-induced migration of fibroblast and endothelial cells.[5]
