这个基因编码肌球蛋白超家族的一个成员该蛋白代表传统的非肌肉肌球蛋白；不应与非传统肌球蛋白-10（myo10）混淆。肌球蛋白是肌动蛋白依赖的运动蛋白，具有多种功能，包括调节胞质分裂、细胞运动和细胞极性。该基因突变与May-Hegglin异常和脑、心脏发育缺陷有关已发现该基因编码不同亚型的多个转录变体。[由RefSeq提供，2011年12月]
This gene encodes a member of the myosin superfamily. The protein represents a conventional non-muscle myosin; it should not be confused with the unconventional myosin-10 (MYO10). Myosins are actin-dependent motor proteins with diverse functions including regulation of cytokinesis, cell motility, and cell polarity. Mutations in this gene have been associated with May-Hegglin anomaly and developmental defects in brain and heart. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]
