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 active in stress fiber. Orthologous to human LIMCH1 (LIM and calponin homology domains 1). [provided by Alliance of Genome Resources, Apr 2022]
