扇贝平滑肌肌球蛋白的两条调节轻链之一 RLC-a 被鸡砂囊肌肌球蛋白轻链激酶完全磷酸化。磷酸化的残基是Ser。它可能是N端11号的Ser。 Ser-11 QRATSNVFA 周围的 9 个残基序列与鸡砂囊肌球蛋白 LC20 的可磷酸化 Ser 周围的序列相同。 RLC-a 也被 cAMP 依赖性蛋白激酶缓慢磷酸化。 RLC-a的磷酸化可能参与扇贝肌肉收缩的调节系统。
One of the two regulatory light chains, RLC-a, of scallop smooth muscle myosin was fully phosphorylated by myosin light chain kinase of chicken gizzard muscle. The residue phosphorylated was Ser. It may be the Ser at number 11 from the N-terminal. The sequence of 9 residues around the Ser-11, QRATSNVFA, is identical with that around the phosphorylatable Ser of LC20 of chicken gizzard myosin. RLC-a was also phosphorylated slowly by cAMP-dependent protein kinase. The phosphorylation of RLC-a may be involved in the regulatory system for the catch contraction of scallop muscle.
