Alpha-actinin-4 is a protein that in humans is encoded by the ACTN4 gene.^[3]

Alpha actinins belong to the spectrin gene superfamily which represents a diverse group of cytoskeletal proteins, including the alpha and beta spectrins and dystrophins. Alpha actinin is an actin-binding protein with multiple roles in different cell types. In nonmuscle cells, the cytoskeletal isoform is found along microfilament bundles and adherens-type junctions, where it is involved in binding actin to the membrane. In contrast, skeletal, cardiac, and smooth muscle isoforms are localized to the Z-disc and analogous dense bodies, where they help anchor the myofibrillar actin filaments. This gene encodes a nonmuscle, alpha actinin isoform which is concentrated in the cytoplasm, and thought to be involved in metastatic processes. Mutations in this gene have been associated with focal and segmental glomerulosclerosis.^[3]

Interactions

Actinin alpha 4 has been shown to interact with PDLIM1,^[4][5] Sodium-hydrogen exchange regulatory cofactor 2,^[6] Collagen, type XVII, alpha 1,^[7] CAMK2A,^[8] CAMK2B,^[8] MAGI1^[9] and TRIM3.^[10]
