Enables filamin binding activity; muscle alpha-actinin binding activity; and myosin heavy chain binding activity. Predicted to be involved in actin cytoskeleton organization; heart development; and muscle structure development. Colocalizes with cortical actin cytoskeleton and stress fiber. Orthologous to human PDLIM2 (PDZ and LIM domain 2). [provided by Alliance of Genome Resources, Apr 2022]
