Class B scavenger receptors are transmembrane proteins that belong to the CD36 family. These receptors contain two transmembrane domains, an extracellular loop with multiple glycosylation sites and two short intracellular tails. They are implicated in lipoprotein scavenging, fatty acid transport, innate immune signalling, cell adhesion, lysosomal protein sorting and gustatory fat detection. (Adapted from FBrf0232659.)
