Final answer:
Rho proteins are small GTPases that regulate cell shape and movement by controlling the actin cytoskeleton. Actin is a globular protein that forms microfilaments and is involved in cellular movement and muscle contraction. Rho proteins interact with actin to regulate the assembly and disassembly of actin filaments.
Step-by-step explanation:
Rho proteins are a group of small GTPases that play a crucial role in regulating cell shape, movement, and organization. They are part of the Rho family of proteins and are involved in signaling pathways that control the reorganization of the actin cytoskeleton.
Actin is a globular protein that forms chains to create microfilaments, which are one of the components of the cytoskeleton. Actin filaments, also known as microfilaments, are intertwined strands of actin that are responsible for cellular movement and muscle contraction. Rho proteins regulate the assembly and disassembly of actin filaments by interacting with actin-binding proteins and controlling the activity of actin-related enzymes.
