Heat shock cognate 71 kDa protein (HSPA8) translocates substrates from cytosol to lysosomal membrane where it binds to Lysosome-associated membrane glycoprotein 2 (LAMP2a). HSPA8 is then released from this complex. Subsequently, Heat shock protein HSP 90 binds to the lysosomal luminal end of LAMP2a (Bandyopadhyay U et al. 2008). This facilitates the multimerization of LAMP2a and internalization of substrate into the lumen. Experiments confirming this binding were performed on rat models.
