anti- LRRC10 antibody

Background

LRRC10 is a heart-specific protein indispensable for proper cardiac development and contractile function. It acts as a cofactor in sarcomeric assembly, ensuring the structural organization of cardiac myofibrils, particularly at the Z-disc. LRRC10's deficiency has been linked to dilated cardiomyopathy (DCM), a condition characterized by ventricular enlargement and systolic dysfunction leading to heart failure. It also plays a role in mechanotransduction, influencing excitation-contraction coupling and calcium handling in cardiomyocytes. Studies involving LRRC10 knockout models reveal embryonic lethality or severe cardiomyopathy phenotypes, underscoring its importance in cardiogenesis. In adult models, LRRC10 dysfunction exacerbates cardiac remodeling under stress conditions, suggesting a protective role in cardiac adaptation. Furthermore, it may regulate sarcomeric protein phosphorylation, influencing contractility. Research is underway to explore its utility as a diagnostic marker or therapeutic target for heart failure, particularly in genetic forms of cardiomyopathy, as mutations in LRRC10 have been found in familial DCM cases, highlighting its clinical significance.
