Solute carrier family 7, member 14 is a protein that in humans is encoded by the SLC7A14 gene. [5]
This gene is predicted to encode a glycosylated, cationic amino acid transporter protein with 14 transmembrane domains. This gene is primarily expressed in skin fibroblasts, neural tissuee, photoreceptor cells, hair cells and primary endothelial cells and its protein is predicted to mediate lysosomal uptake of cationic amino acids. In mice, this gene is expressed in the photoreceptor layer of the retina where its expression increases over the course of retinal development and persists in the mature retina. The gene is also highly expressed in all vertebrate hair cells. In the mammalian inner ear, this gene is expressed in neonatal inner and outer hair cells during development and becomes specifically expressed in inner hair cells in adult animals,. [6] [7] Mutations in this gene are associated with autosomal recessive retinitis pigmentosa and hearing loss in the form of auditory neuropathy.
Retinitis pigmentosa (RP) is a member of a group of genetic disorders called inherited retinal dystrophy (IRD) that cause 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.
The photoreceptor cell-specific nuclear receptor (PNR), also known as NR2E3, is a protein that in humans is encoded by the NR2E3 gene. PNR is a member of the nuclear receptor super family of intracellular transcription factors.
Usherin is a protein that in humans is encoded by the USH2A gene.
Hexokinase I, also known as hexokinase A and HK1, is an enzyme that in humans is encoded by the HK1 gene on chromosome 10. Hexokinases phosphorylate glucose to produce glucose-6-phosphate (G6P), the first step in most glucose metabolism pathways. This gene encodes a ubiquitous form of hexokinase which localizes to the outer membrane of mitochondria. Mutations in this gene have been associated with hemolytic anemia due to hexokinase deficiency. Alternative splicing of this gene results in five transcript variants which encode different isoforms, some of which are tissue-specific. Each isoform has a distinct N-terminus; the remainder of the protein is identical among all the isoforms. A sixth transcript variant has been described, but due to the presence of several stop codons, it is not thought to encode a protein. [provided by RefSeq, Apr 2009]
Peropsin, a visual pigment-like receptor, is a protein that in humans is encoded by the RRH gene. It belongs like other animal opsins to the G protein-coupled receptors. Even so, the first peropsins were already discovered in mice and humans in 1997, not much is known about them.
RPE-retinal G protein-coupled receptor also known as RGR-opsin is a protein that in humans is encoded by the RGR gene. RGR-opsin is a member of the rhodopsin-like receptor subfamily of GPCR. Like other opsins which bind retinaldehyde, it contains a conserved lysine residue in the seventh transmembrane domain. RGR-opsin comes in different isoforms produced by alternative splicing.
X-linked retinitis pigmentosa GTPase regulator is a GTPase-binding protein that in humans is encoded by the RPGR gene. The gene is located on the X-chromosome and is commonly associated with X-linked retinitis pigmentosa (XLRP). In photoreceptor cells, RPGR is localized in the connecting cilium which connects the protein-synthesizing inner segment to the photosensitive outer segment and is involved in the modulation of cargo trafficked between the two segments.
ATP-binding cassette, sub-family A (ABC1), member 4, also known as ABCA4 or ABCR, is a protein which in humans is encoded by the ABCA4 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.
Retinaldehyde-binding protein 1 (RLBP1) also known as cellular retinaldehyde-binding protein (CRALBP) is a 36-kD water-soluble protein that in humans is encoded by the RLBP1 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.
Neural retina-specific leucine zipper protein is a protein that in humans is encoded by the NRL gene.
Tubby-related protein 1 is a protein that in humans is encoded by the TULP1 gene.
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.
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.
Cationic amino acid transporter 4 is a protein that in humans is encoded by the SLC7A4 gene.
