WebOtopetrin1 (Otop1) is a multitransmembrane domain protein required for the formation of otoconia in the vertebrate inner ear. Otoconia are complex calcium carbonate (CaCO 3) biominerals that are required for the sensation of gravity.Examination of the phenotypes of animals with mutations or deficiencies in Otop1 suggests a direct role for Otop1 in the … The otopetrin family is a group of proteins that were first identified based on their essential role in the vestibular system, and were later shown to form proton-selective ion channels expressed in many different tissues, including taste receptor cells. They are named after the Greek word "o̱tós," which means ear and "pétrā," which means rock, in reference to their role in the formation of oto… ready my clicker
