Predicted to enable myosin II head/neck binding activity. Predicted to be involved in several processes, including cytoplasmic actin-based contraction involved in cell motility; positive regulation of stress fiber assembly; and regulation of focal adhesion assembly. Predicted to be located in cytoplasm and cytoskeleton. Predicted to be part of myosin II complex. Predicted to be active in stress fiber. Is expressed in several structures, including eye; gonad; gut; hemolymphoid system gland; and nervous system. Orthologous to human LIMCH1 (LIM and calponin homology domains 1).
