资源简介:
PAK2, activated by CDC42 or RAC1 RHO GTPases, phosphorylates myosin regulatory light chain (MRLC, MYL9 or MYL12B) of the non-muscle myosin II complex on threonine residue T19 (also labeled in literature as T18). This leads to the rearrangement of the actin cytoskeleton and cell retraction (Chew et al. 1998, Zeng et al. 2000).
PAK2,由CDC42或RAC1 RHO GTPases激活,在非肌肉肌球蛋白II复合体的肌球蛋白调节轻链(MRLC,MYL9或MYL12B)的苏氨酸残基T19上进行磷酸化(在文献中也标记为T18)。这导致细胞骨架的重新排列和细胞收缩(Chew等人,1998年,Zeng等人,2000年)。
