Final Answer:
False. Proteins that provide a template for polymerization of actin filaments are called actin nucleating proteins.
Step-by-step explanation:
The statement is almost correct but has a slight error in terminology. Proteins that facilitate the initiation and serve as a template for the polymerization of actin filaments are indeed referred to as actin nucleating proteins, not just nucleating proteins. Actin nucleating proteins play a crucial role in regulating the assembly of actin filaments, which are essential components of the cytoskeleton involved in various cellular processes such as cell motility, shape maintenance, and intracellular transport.
Examples of actin nucleating proteins include the Arp2/3 complex and formins. These proteins promote the nucleation of actin monomers, which then go on to form the polymerized actin filaments.
