Depositor Comments

This is Gq alpha with the C-terminal amino acids changed from Gq alpha to Gz alpha residues (EYNLV to YIGLC). Works the same as qi5 and is the least popular since no one knows what Gz alpha really does in nature. Since qz5 is not sensitive to pertussis toxin, qz5 may be the only G protein activated by a Gi-coupled receptor in cells treated with pertussis toxin. This trick can be experimentally useful in settings where you want experimental control of the exact G protein and the receptor that is activated. It is theoretically possible that this construct will work better than the other constructs for particular receptors, but the Conklin lab has not seen this happen yet.

Contains an internal hemaglutinin epitope tag (DVPDYA) that has no effect on receptor coupling.
