Summary
Enables several functions, including actin monomer binding activity; phosphatidylinositol-4,5-bisphosphate binding activity; and proline-rich region binding activity. Involved in intracellular transport; mitotic actomyosin contractile ring assembly; and positive regulation of formin-nucleated actin cable assembly. Located in cytosol. Used to study amyotrophic lateral sclerosis and amyotrophic lateral sclerosis type 18. Orthologous to human PFN4 (profilin family member 4). [provided by Alliance of Genome Resources, Apr 2025]
