ROCK1 protein stands as a pivotal kinase, wielding key regulatory influence over the actin cytoskeleton and cellular polarity. Demonstrating a broad spectrum of cellular functions, ROCK1 intricately governs smooth muscle contraction, actin cytoskeleton organization, stress fiber and focal adhesion formation, neurite retraction, cell adhesion, and motility through the phosphorylation of diverse substrates such as DAPK3, GFAP, LIMK1, LIMK2, MYL9/MLC2, TPPP, PFN1, and PPP1R12A. It collaborates with FHOD1 to induce SRC-dependent non-apoptotic plasma membrane blebbing and phosphorylates JIP3, regulating the recruitment of JNK to JIP3 during UVB-induced stress. As a suppressor of inflammatory cell migration, ROCK1 influences PTEN phosphorylation and stability, while concurrently acting as a negative regulator of VEGF-induced angiogenic endothelial cell activation. Crucially involved in centrosome positioning and mitotic exit, ROCK1 plays roles in terminal erythroid differentiation, inhibition of podocyte motility, promotion of keratinocyte terminal differentiation, and facilitation of osteoblast compaction during matrix assembly, contributing to osteoblast mineralization. Moreover, ROCK1 may impact eyelid and ventral body wall closure through the induction of actomyosin bundle assembly. The diverse roles of ROCK1 underscore its multifaceted impact on cellular physiology and highlight its regulatory significance in various cellular processes.
