Phosphorylation of desmin filament by cdc2 kinase induced a transition toward the depolymerized state of the filament. Sequence analysis of purified phosphopeptides derived from cdc2 kinase-phosphorylated desmin revealed that Ser-6, Ser-22 and Thr-64 in the N-terminal head domain were the sites phosphorylated.
细胞周期蛋白依赖性激酶2（cdc2激酶）使结蛋白丝磷酸化，导致丝向解聚状态转变。对源自cdc2激酶磷酸化结蛋白的纯化磷酸肽进行序列分析，结果显示N端头部结构域中的丝氨酸-6、丝氨酸-22和苏氨酸-64是磷酸化位点。
