Background: Chondroadherin

Chondroadherin (CHAD), also known as SLRR4A, is a 38-kDa secreted protein belonging to the small leucine-rich proteoglycans (SLRPs) that help regulate the assembly and function of the ECM (1). CHAD is highly expressed in cartilaginous tissues, with lower expression levels found in bone, tendon, and eye (2-4). Mature human CHAD consists of a 337 amino acid (aa) protein that contains eleven leucine-rich repeats (LRRs) including nine tandem leucine-rich repeats as well as N-terminal and C-terminal leucine-rich domains flanked by cysteine-rich regions (5). CHAD interacts with collagen II and mediates signaling between chondrocytes and the ECM by binding to the alpha2 beta1 integrin, heparan sulphate, and to cell surface proteoglycans like syndecans (5-9). In addition, CHAD interacts with both N- and C-terminal globular domains of type VI collagen (10). Human CHAD shares 95% and 94% aa sequence identity with mouse and rat CHAD, respectively.
