Lamp2 Gene Summary [Rat]
Predicted to enable several functions, including enzyme binding activity; ion channel inhibitor activity; and signaling adaptor activity. Involved in chaperone-mediated autophagy. Acts upstream of or within protein targeting to lysosome involved in chaperone-mediated autophagy. Located in endosome; lysosome; and membrane raft. Used to study Danon disease; cholestasis; chronic conjunctivitis; cognitive disorder; and hypertrophic cardiomyopathy. Biomarker of myocardial infarction; sciatic neuropathy; and traumatic brain injury. Human ortholog(s) of this gene implicated in Danon disease and hypertrophic cardiomyopathy. Orthologous to human LAMP2 (lysosomal associated membrane protein 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Lamp2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
