Predicted to enable actin filament binding activity and alpha-actinin binding activity. Predicted to be involved in actin filament organization. Predicted to act upstream of or within cardiac muscle tissue morphogenesis; cell-cell junction organization; and ventricular septum development. Predicted to be located in Z disc. Predicted to colocalize with focal adhesion and stress fiber. Orthologous to human XIRP2 (xin actin binding repeat containing 2). [provided by Alliance of Genome Resources, Apr 2022]
