A	PF12194	Ste5, vWA domain (Ste5_C)	Ste5, vWA domain	This entry represents the C-terminal domain of Ste5, which contains a vWA fold. It is also referred to as the minimal scaffold domain [2]. This domain is required for Fus3 co-activation together with active MAPKK Ste7 [3]. It binds tightly to Ste7 [2 ...	This entry represents the C-terminal domain of Ste5, which contains a vWA fold.
