The phosphorylatable light chain from uterine and arterial smooth muscles appear as four spots on two-dimensional gel electrophoretograms due to the existence of isoforms which may be non-, mono- or diphosphorylated. 2. The phosphorylation sites are serine and threonine residues; the phosphoserine to phosphothreonine ratio is smaller, and the extent of diphosphorylation is larger in uterus than in artery. 3. Different phosphorylation values found at identical tension levels and identical phosphorylation values found at different tension levels narrow the role of light chain phosphorylation to the activation of smooth muscle contraction.

由于存在可能未磷酸化、单磷酸化或双磷酸化的同工型，子宫和动脉平滑肌的可磷酸化轻链在二维凝胶电泳图谱上呈现为四个斑点。2. 磷酸化位点是丝氨酸和苏氨酸残基；子宫中磷酸丝氨酸与磷酸苏氨酸的比值较小，双磷酸化程度比动脉中更大。3. 在相同张力水平下发现不同的磷酸化值，以及在不同张力水平下发现相同的磷酸化值，这将轻链磷酸化的作用缩小到平滑肌收缩的激活。
