Lysosomal Associated Membrane Protein 2 (LAMP2) Antibody (APC)

Background

Lysosome-associated membrane glycoprotein 2 (LAMP2) is a critical lysosomal membrane protein involved in autophagy, lysosomal biogenesis, and cellular homeostasis LAMP2 facilitates the fusion of autophagosomes with lysosomes, enabling the degradation of cellular components during autophagy LAMP2 exists in three isoforms (LAMP2A, LAMP2B, and LAMP2C), each with distinct roles in lysosome function LAMP2A is essential for chaperone-mediated autophagy (CMA), where it mediates the selective degradation of cytosolic proteins LAMP2B is primarily involved in macroautophagy, particularly in muscle and neuronal tissues Mutations in LAMP2 cause Danon disease, a rare lysosomal storage disorder characterized by cardiomyopathy, myopathy, and intellectual disability LAMP2 dysregulation has been linked to neurodegenerative diseases and cancers, where impaired autophagy disrupts cellular homeostasis and promotes disease progression LAMP2 also plays a role in immune responses, contributing to antigen processing and lysosomal exocytosis Its importance in autophagy, cellular stress responses, and disease underscores its critical role in maintaining cellular integrity
