Automated description from the Alliance of Genome Resources (Release 7.4.0)
Enables actin filament binding activity. A structural constituent of cytoskeleton. Involved in several processes, including bicellular tight junction assembly; podocyte cell migration; and protein localization to bicellular tight junction. Acts upstream of or within gene expression. Located in several cellular components, including Z disc; focal adhesion; and pseudopodium. Colocalizes with stress fiber. Is expressed in early conceptus and heart. Used to study focal segmental glomerulosclerosis 1. Human ortholog(s) of this gene implicated in focal segmental glomerulosclerosis and focal segmental glomerulosclerosis 1. Orthologous to human ACTN4 (actinin alpha 4).
