**Background of Trim63 Recombinant Protein**
Trim63 (Tripartite Motif-containing 63), also known as Muscle RING-finger protein-1 (MuRF1), is a member of the TRIM protein family characterized by conserved RING, B-box, and coiled-coil domains. It functions as an E3 ubiquitin ligase, playing a critical role in ubiquitin-mediated protein degradation via the proteasome system. Primarily expressed in striated muscle, Trim63 is a key regulator of muscle atrophy under conditions such as fasting, denervation, or diseases like cancer cachexia and diabetes. It targets structural proteins, including sarcomeric components (e.g., troponin, myosin heavy chains), for degradation, thereby modulating muscle mass and function.
The recombinant Trim63 protein is produced through genetic engineering, often using bacterial or mammalian expression systems, to enable in vitro studies of its molecular mechanisms. Its purified form retains enzymatic activity, allowing researchers to investigate substrate interactions, ubiquitination processes, and regulatory pathways. Recombinant Trim63 is widely used to explore muscle-wasting pathologies, screen potential inhibitors for therapeutic development, or validate binding partners in signaling cascades.
Studies highlight its involvement in stress-responsive pathways, such as the FoxO and NF-κB axes, linking it to both physiological remodeling and pathological atrophy. Its role extends beyond muscle; emerging evidence suggests implications in cardiac hypertrophy and metabolic disorders. The availability of recombinant Trim63 has accelerated drug discovery efforts, particularly in designing targeted therapies to mitigate muscle loss while preserving critical cellular functions. However, challenges remain in balancing its inhibition to avoid unintended effects on protein homeostasis. Overall, Trim63 recombinant protein serves as a vital tool for dissecting the molecular basis of muscle atrophy and developing precision interventions.
