这个基因编码一种细胞骨架蛋白，这是组织肌动蛋白细胞骨架所必需的。这种蛋白质是含有肌动蛋白微丝的一种成分，它参与控制细胞的形状、粘附和收缩。该基因多态性与1型胰腺癌易感性相关，也与心肌梗死风险相关。选择性剪接导致多个转录变体。[由RefSeq提供，2009年10月]
This gene encodes a cytoskeletal protein that is required for organizing the actin cytoskeleton. The protein is a component of actin-containing microfilaments, and it is involved in the control of cell shape, adhesion, and contraction. Polymorphisms in this gene are associated with a susceptibility to pancreatic cancer type 1, and also with a risk for myocardial infarction. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]
