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, cytoskeletal, alpha actinin isoform and maps to the same site as the structurally similar erythroid beta spectrin gene. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
A study in humans demonstrated that the ACTN1 gene was downregulated during short-term weight loss in subcutaneous adipose tissue [Bollepalli et al. DOI:10.1038/ijo.2017.245], while a separate investigation in humans found that the ACTN1 gene expression increased sharply in peripheral blood samples from patients with post-myocardial infarction heart failure compared to non-heart failure patients and was part of a validated 13-gene predictive signature [Sun et al. DOI:10.3389/fimmu.2023.1163350]. A study in mice demonstrated that the ACTN1 gene (Actn1) was downregulated (0.446-fold reduction) in lung tissue following hypothermia-induced death, identifying it as a candidate forensic biomarker for this condition [Takamiya et al. DOI:10.1016/J.Legalmed.2020.101789].
