Predicted to enable enzyme inhibitor activity and myosin phosphatase regulator activity. Involved in several processes, including germline ring canal formation; neuron differentiation; and regulation of compound eye photoreceptor development. Located in apical cortex. Colocalizes with apical junction complex. Is expressed in several structures, including embryonic/larval esophageal visceral muscle; female germline cyst; germarium; larval muscle cell; and larval muscle system. Orthologous to several human genes including PPP1R12B (protein phosphatase 1 regulatory subunit 12B).
FB Description
Myosin binding subunit (Mbs) encodes a regulatory subunit of myosin phosphatase. It interacts with the catalytic subunit of the myosin phosphatase encoded by flw. It is involved in cell movement in various biological processes and in the arrest of constriction of contractile rings and ring canals during oogenesis.
