Creatine kinase M (CKM) is a cytosolic enzyme that plays a central role in cellular energy homeostasis by catalyzing the reversible transfer of phosphate between phosphocreatine and ADP to regenerate ATP. This reaction is essential in tissues with high and fluctuating energy demands, particularly skeletal and cardiac muscle where rapid ATP turnover is required for contraction and mechanical work. Creatine Kinase M Antibody is commonly used to study this enzyme in muscle tissue, where it serves as a key marker of energy metabolism and contractile activity.
CKM belongs to the creatine kinase family of phosphotransferases, which includes multiple cytosolic and mitochondrial isoforms that collectively regulate intracellular energy distribution. The M-type subunit forms homodimers (CK-MM) that are highly enriched in skeletal muscle, as well as heterodimers (CK-MB) in cardiac tissue when combined with the B-type subunit. CKM antibody, also known as Creatine kinase M antibody or Muscle creatine kinase antibody in the literature, supports detection of this isoform in pathways associated with ATP regeneration, phosphocreatine cycling, and muscle-specific metabolic function.
Functionally, CKM operates within the phosphocreatine shuttle, a system that rapidly delivers high-energy phosphate groups from sites of ATP production to sites of ATP consumption. In muscle cells, this process is critical for sustaining repeated contraction cycles, maintaining ion gradients, and supporting cytoskeletal dynamics during mechanical stress. Alterations in CKM expression or activity have been associated with muscle injury, metabolic disorders, and cardiac dysfunction, making it a widely studied marker in both physiological and pathological contexts. Creatine Kinase M Antibody enables investigation of these changes at the protein level in tissue and lysate-based analyses.
Subcellularly, CKM is primarily localized in the cytoplasm of muscle cells, where it is often associated with myofibrillar structures and regions of high ATP utilization. This localization supports efficient energy transfer during contraction and contributes to characteristic cytoplasmic staining patterns in tissue-based assays. In skeletal muscle, strong and uniform expression is typically observed in myocytes, while in cardiac tissue expression reflects the metabolic demands of continuous contraction. CKM antibody is therefore well suited for evaluating muscle-specific protein expression and metabolic activity.
This Creatine Kinase M Antibody is supported by immunohistochemistry and western blot data demonstrating detection of CKM in relevant tissue samples. Protein microarray specificity validation confirms selective binding to CKM among a large panel of human proteins, providing strong confidence in target specificity and reducing the likelihood of cross-reactivity. Together, these features support its use in studies of muscle metabolism, contractile function, and energy regulation.
