Background

LIMPII (Lysosomal Integral Membrane Protein II), also known as LPG85 (85 kDa lysosomal membrane sialoglycoprotein) and CD36 antigen-like 2 (CD36L2), is a major lysosomal membrane protein. It belongs to the scavenger receptor class B subfamily and is designated member 2 (SR-B2). Other mammalian members of this family include SR-B1 (alternatively known as Cla-1 and CD36L1), and SR-B3 (CD36) (1‑3). SR-B/CD36 family members are type III integral membrane proteins with an N‑ as well as a C-terminal cytoplasmic tail, and a large extracellular (or luminal in the case of LIMPII) loop containing similarly spaced cysteine residues and multiple glycosylation sites. The C-terminal cytoplasmic tail has a di-leucine-based motif that mediates effective lysosomal targeting. LIMPII is expressed on all tissues and cell types examined so far, including activated platelets. LIMPII binds thrombospondin-1, but the biological significance of this interaction is not known. LIMPII‑thrombospondin interaction may contribute to the pro-adhesive changes of activated platelets during coagulation and inflammation (1). Overexpression of LIMPII causes an enlargement of early and late endosomes, suggesting that LIMPII may play a role in lysosome/endosome biogenesis (4). Mice deficient in LIMPII are impaired in membrane transport processes, resulting in ureteric pelvic junction obstruction, deafness and peripheral neuropathy (5).
