Clusterin (CLU, also known as apolipoprotein J) is a member of the small heat shock protein family and a molecular chaperone associated with the clearance of cellular debris and apoptosis. The secretory isoform of CLU is a heterodimeric, disulfide-linked glycoprotein composed of two subunits of 40 kDa alpha- and beta-chains. CLU is a Golgi chaperone that facilitates the folding of secreted proteins in an ATP-independent way. CLU is widely distributed in many tissues and organs, where it participates in a number of biological processes, including lipid transport, membrane recycling, cell adhesion, programmed cell death, and complement-mediated cell lysis. Through this function, CLU is involved in many diseases related to oxidative stress, including neurodegenerative diseases, cancers, inflammatory diseases, and aging. CLU activity is also involved in infectious diseases, such as hepatitis C. As evident by its key roles in cancer development, CLU can serve as a therapeutic target for fighting tumor growth and chemoresistance.
