Tubby-related protein 1 is a protein that in humans is encoded by the TULP1 gene. [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]
Retinitis pigmentosa (RP) is a genetic disorder of the eyes that causes loss of vision. Symptoms include trouble seeing at night and decreasing peripheral vision. As peripheral vision worsens, people may experience "tunnel vision". Complete blindness is uncommon. Onset of symptoms is generally gradual and often begins in childhood.
Usherin is a protein that in humans is encoded by the USH2A gene.
Peripherin-2 is a protein, that in humans is encoded by the PRPH2 gene. Peripherin-2 is found in the rod and cone cells of the retina of the eye. Defects in this protein result in one form of retinitis pigmentosa, an incurable blindness.
PRP31 pre-mRNA processing factor 31 homolog , also known as PRPF31, is a protein which in humans is encoded by the PRPF31 gene.
Protein XRP2 is a protein that in humans is encoded by the RP2 gene.
S-arrestin is a protein that in humans is encoded by the SAG gene.
Crumbs homolog 1 is a protein that in humans is encoded by the CRB1 gene.
Keratocan (KTN) also known as keratan sulfate proteoglycan keratocan, is a protein that in humans is encoded by the KERA gene.
Aryl-hydrocarbon-interacting protein-like 1 is a protein that in humans is encoded by the AIPL1 gene.
Cyclic nucleotide gated channel beta 3, also known as CNGB3, is a human gene encoding an ion channel protein.
Rod outer segment membrane protein 1 is a protein that in humans is encoded by the ROM1 gene.
Oxygen-regulated protein 1 also known as retinitis pigmentosa 1 protein (RP1) is a protein that in humans is encoded by the RP1 gene.
Hemicentin-1 is a protein that in humans is encoded by the HMCN1 gene.
Cyclic nucleotide gated channel beta 1, also known as CNGB1, is a human gene encoding an ion channel protein.
Rod cGMP-specific 3',5'-cyclic phosphodiesterase subunit alpha is an enzyme that in humans is encoded by the PDE6A gene.
Fascin-2 is a protein that in humans is encoded by the FSCN2 gene.
Cytochrome P450 4V2 is a protein that in humans is encoded by the CYP4V2 gene.
Membrane frizzled-related protein is a protein that in humans is encoded by the MFRP gene.
Inosine-5'-monophosphate dehydrogenase 1, also known as IMP dehydrogenase 1, is an enzyme that in humans is encoded by the IMPDH1 gene.
Retinal degeneration is a retinopathy which consists in the deterioration of the retina caused by the progressive death of its cells. There are several reasons for retinal degeneration, including artery or vein occlusion, diabetic retinopathy, R.L.F./R.O.P., or disease. These may present in many different ways such as impaired vision, night blindness, retinal detachment, light sensitivity, tunnel vision, and loss of peripheral vision to total loss of vision. Of the retinal degenerative diseases retinitis pigmentosa (RP) is a very important example.
