Summaries for ACTN2 Gene

Entrez Gene Summary for ACTN2 Gene

  • 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 muscle-specific, alpha actinin isoform that is expressed in both skeletal and cardiac muscles. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2013]

GeneCards Summary for ACTN2 Gene

ACTN2 (Actinin Alpha 2) is a Protein Coding gene. Diseases associated with ACTN2 include cardiomyopathy, dilated, 1aa, with or without lvnc and actn2-related dilated cardiomyopathy. Among its related pathways are Adherens junction and Amoebiasis. GO annotations related to this gene include calcium ion binding and protein dimerization activity. An important paralog of this gene is SYNE2.
