| 背景 | <p>Myosin is composed of six polypeptide chains: two identical heavy chains and two pairs of light chains. Myosin light chain 2 (MLC2), also known as myosin regulatory light chain (MRLC), RLC, or LC20, has many isoforms with varying tissue distribution. Smooth muscle MLC2 is phosphorylated at Thr18 and Ser19 by myosin light chain kinase (MLCK) in a Ca<sup>2+</sup>/calmodulin-dependent manner (1). These phosphorylation events are correlated with myosin ATPase activity and smooth muscle contraction (2). Striated muscle contraction is regulated by the troponin-tropomyosin complex in thin actin filaments and by binding of Ca<sup>2+</sup> to troponin C (3). Two types of myosin light chain are expressed in the heart, with myosin light chain 2v (MYL2, MLC-2v) expression restricted to the ventricles and myosin light chain 2a (MYL7, MLC-2a) found specific to the atria. Mutations in the corresponding <i>MYL2</i> gene are found in patients diagnosed with a form of hypertrophic cardiomyopathy characterized by thickening of the mid-left ventricle.</p>肌球蛋白由6条多肽链构成：两条相同的重链和两组轻链。肌球蛋白轻链2（MLC2），也被称为肌球蛋白调节轻链（MRLC），RLC或LC20，有许多取决于其分布的不同亚型。在平滑肌中，MLC2会被肌球蛋白轻链激酶（MLCK）在Ca2+/calmodulin依赖的状态下磷酸化第18位苏氨酸和19位丝氨酸（1）。这种磷酸化与肌球蛋白ATPase活性和平滑肌收缩性相关（2）。ROCK也会磷酸化平滑肌MLC2的19位丝氨酸，这会调节应力纤维的集合（3）。心脏中表达两种类型的肌球蛋白轻链，肌球蛋白轻链2v(MYL2, MLC-2v)表达限制在心室中，肌球蛋白轻链2a(MYL7, MLC-2a)的特异性表达在心房中。中左心房过厚引起的心肌肥大病人发现他们的MYL2基因发生了突变。 |
