**Background of TMOD4 Recombinant Protein**
Tropomodulin 4 (TMOD4), a member of the tropomodulin family, is a cytoskeletal regulatory protein primarily expressed in striated muscles, including skeletal and cardiac tissues. It plays a critical role in stabilizing actin filaments by capping their pointed ends, thereby regulating actin dynamics—a process essential for maintaining sarcomere structure and muscle contractility. TMOD4 binds to both actin and tropomyosin, forming a ternary complex that fine-tunes thin filament length and stability during myofibrillogenesis.
Structurally, TMOD4 contains a conserved N-terminal actin-binding domain and a C-terminal tropomyosin-binding domain. Its expression is tightly regulated during muscle development and regeneration. Dysregulation of TMOD4 has been implicated in muscle-related pathologies, such as cardiomyopathies and muscular dystrophies, highlighting its physiological importance.
Recombinant TMOD4 protein is engineered using expression systems like *E. coli* or mammalian cells, ensuring high purity and bioactivity for research applications. It serves as a vital tool for studying actin cytoskeleton dynamics, muscle cell mechanics, and molecular pathways underlying muscle disorders. Additionally, recombinant TMOD4 aids in drug discovery efforts targeting cytoskeletal abnormalities, offering insights into therapeutic strategies for neuromuscular and cardiovascular diseases. Its study bridges gaps in understanding how cytoskeletal regulation impacts cellular resilience and disease progression.
