Predicted to enable actin filament binding activity and enzyme binding activity. Predicted to be a structural constituent of cytoskeleton. Predicted to contribute to protein-macromolecule adaptor activity. Predicted to be involved in Arp2/3 complex-mediated actin nucleation. Predicted to be located in several cellular components, including actin cytoskeleton; cell projection; and nucleus. Predicted to be part of Arp2/3 protein complex. Is expressed in dorsal root ganglion. Used to study psoriasis. Orthologous to several human genes including ARPC4-TTLL3 (ARPC4-TTLL3 readthrough). [provided by Alliance of Genome Resources, Apr 2022]
