WebSep 20, 2024 · The level of actin/PLC-ζ interaction was twice as high in G-actin ( P < 0.001) that reflected an increase in affinity. Upon reaching the AR spermatozoa, PLC-ζ was partially released from the cell. It was concluded that actin cytoskeleton dynamics control the migration of PLC-ζ during capacitation and leads to its partial release at AR spermatozoa. Web76%.
