Retinoschisin also known as X-linked juvenile retinoschisis protein is a protein that in humans is encoded by the RS1 gene.^[3]^[4]^[5]

Function and Cell Biology

Retinoschisin is an extracellular protein that plays a crucial role in the cellular organization of the retina. This protein is assembled and secreted from photoreceptors and bipolar cells as a homo-oligomeric protein complex.^[5] Monomeric retinoschisin contains 224 amino acids with a leader sequence that is cleaved off upon preparation in the cell for secretion.^[3]

Clinical significance

Mutations in this gene are responsible for X-linked retinoschisis an early-onset macular degeneration in males that results in a splitting of the inner layers of the retina and severe loss in vision.^[5]
