**Background of WHAMM Protein**
WHAMM (WASP Homolog Associated with Actin, Membranes, and Microtubules) is a multidomain scaffolding protein involved in regulating cytoskeletal dynamics. It plays a critical role in cellular processes such as vesicle trafficking, organelle positioning, and membrane remodeling. WHAMM interacts with both actin filaments and microtubules, acting as a bridge to coordinate their remodeling during cellular morphogenesis and intracellular transport.
Structurally, WHAMM contains an N-terminal WASP Homology 2 (WH2) domain that promotes actin polymerization by recruiting the Arp2/3 complex, a middle membrane-binding region, and a C-terminal microtubule-interacting domain. This dual affinity for actin and microtubules allows WHAMM to facilitate cross-talk between the two cytoskeletal systems, influencing processes like Golgi organization and autophagosome formation.
Studies link WHAMM dysfunction to diseases, including neurodegenerative disorders and cancer metastasis, due to its role in cell motility and membrane trafficking. Recombinant WHAMM protein, produced via genetic engineering in bacterial or eukaryotic systems, is widely used in vitro to dissect its molecular interactions, structural domains, and regulatory mechanisms. Its study provides insights into cytoskeletal coordination and potential therapeutic targets for cytoskeleton-related pathologies.
