Enables ubiquitin protein ligase binding activity. A structural constituent of postsynaptic actin cytoskeleton. Involved in regulation of apoptotic process and response to hypoxia. Located in neuron projection and stress fiber. Part of protein-containing complex. Is active in glutamatergic synapse and postsynaptic actin cytoskeleton. Human ortholog(s) of this gene implicated in focal segmental glomerulosclerosis and focal segmental glomerulosclerosis 1. Orthologous to human ACTN4 (actinin alpha 4); PARTICIPATES IN platelet-derived growth factor signaling pathway; arrhythmogenic right ventricular cardiomyopathy pathway; Entamoebiasis pathway; INTERACTS WITH 2,2,2-tetramine; 2,3,7,8-tetrachlorodibenzodioxine; 2,6-dinitrotoluene.
[[Gasoline co-treated with 1-Butanol] results in increased abundance of [Particulate Matter co-treated with Polycyclic Aromatic Hydrocarbons]] which results in increased expression of ACTN4 mRNA
[perfluorooctane sulfonic acid co-treated with Cellulose] results in decreased expression of ACTN4 mRNA and [perfluorooctane sulfonic acid co-treated with Inulin] results in decreased expression of ACTN4 mRNA
[LDN 193189 co-treated with 4-(5-benzo(1 and 3)dioxol-5-yl-4-pyridin-2-yl-1H-imidazol-2-yl)benzamide co-treated with FGF2 protein] results in decreased expression of ACTN4 protein
