Background: Otolin-1

Otolin (OTOL1), also known as C1qTNF15, is an approximately 65 kDa protein found in the otoconial membrane lining the cochlea and vestibular labyrinth of the inner ear (1). It is secreted by supporting cells of the sensory epithelium. The otoconial membrane contains particles known as otoconia which are composed of glycoproteins and proteoglycans coated with calcium carbonate crystals. Otolin is one of the protein components of otoconia particles, and it is important for otoconia formation as well as for auditory and vestibular function (1). It associates into multimers and disulfide-linked oligomers and also associates with other otoconial proteins including and Otoconin-90 (also known as PLA2G2A, PLA2L, and phospholipase A2 homolog) and Cerebellin-1 (1-3). Otolin contains three collagen-like regions followed by a C1q-like domain at the C-terminus (4). It is extensively glycosylated and has multiple hydroxylated proline residues in the collagenous regions. Human Otolin shares 72% amino acid sequence identity with mouse and rat Otolin.
