Predicted to enable actin filament binding activity. Predicted to be involved in actin filament organization and negative regulation of protein binding activity. Predicted to act upstream of or within several processes, including Notch signaling pathway; muscle cell development; and negative regulation of cell population proliferation. Predicted to be located in adherens junction and fascia adherens. Predicted to colocalize with focal adhesion and stress fiber. Orthologous to human XIRP1 (xin actin binding repeat containing 1).
