Tubby-related protein 1 is a protein that in humans is encoded by the TULP1gene.[5][6][7]
TULP1 is a member of a family of tubby-like genes (TULPs) that encode proteins of unknown function. Members of this family have been identified in plants, vertebrates, and invertebrates.
The TULP proteins share a conserved C-terminal region of approximately 200 amino acid residues. TULP1 is a candidate gene for retinitis pigmentosa-14 (RP). Mutation in TULP1 is a rare cause of recessive RP and TULP1 plays an essential role in the physiology of photoreceptors.[7]
