Question

A key group of proteins that regulate the actin cytoskeleton is:

A. the Rho protein family.
B. the Rab protein family.
C. the Ran protein family.
D. the Ras protein family.

Answer 1

The key group of proteins that regulate the actin cytoskeleton is the Rho protein family.

Step-by-step explanation:

The key group of proteins that regulate the actin cytoskeleton is the Rho protein family. These proteins play a crucial role in controlling actin dynamics and cytoskeletal rearrangements. They are involved in various cellular processes such as cell migration, cell shape changes, and cytokinesis.
