41. Actin polymerization can further be regulated by profilin and cofilin.42. DNase I binds to the affinity and actin polymers with lower affinity. 43. Also 3 different forms of actin were identified during myogenesis. 44. Arf GTPase families are involved in actin cytoskeleton dynamics and vesicular trafficking. 45. Without it, smooth muscle ? actin is markedly reduced. 46. Activated ROCK1 phosphorylates MLC involved in actin -myosin contractility. 47. Beta-actin has been shown to interact with SPTBN2. 48. It is thought to regulate actin polymerization in response to extracellular signals. 49. This enzyme participates in phosphatidylinositol signaling system and regulation of actin cytoskeleton. 50. Through Rac1 / CDC42, IQGAP1 regulates cellular adhesion and actin dynamics.
