Description

Myosin IX is a processive single-headed motor, which might play a role in signalling. Class IX myosins contain a GTPase-activating protein (GAP) domain in their tail region, which allows them to negatively regulate small Rho GTPases [PMID: 12471888]. This entry represents the catalytic (head) domain, which has ATPase activity and belongs to the larger group of P-loop NTPases. The single head of class IX myosin exhibits characteristics of a processive motor [PMID: 20538589, PMID: 20627400].
