question: Which is the receptor for substrates of Chaperone Mediated Autophagy?
answer: Chaperone-mediated autophagy (CMA) is a lysosomal pathway for selective removal of damaged cytosolic proteins. The LAMP2A (Lysosome-associated membrane protein 2 isoform A) functions as a receptor for cytosolic proteins and also as essential component of the CMA translocation complex [28]. Cytosolic substrate proteins bind to monomers of LAMP-2A, which then multimerizes to form the complex required for substrate transmembrane import.
