Prominin is the first identified member of a new type of membrane - proteins in animal cells (specifically a glycoprotein ). It has an unusual structure with five areas penetrating the membrane and two large extracellular loops protruding from the membrane. It has been found in stem cells , epithelial cells, and nonepithelial cells, as well as in retinal photoreceptor cells . Prominin interacts with membrane cholesterol and is a marker for a lipid derived from cholesterol called raft . If there is a mutation in the human gene responsible for producing the protein (whereby the protein is shortened), retinal degeneration usually occurs .
