Rhodopsin: Rhodopsin (also known as visual purple) is a light-sensitive receptor protein. It is named after ancient Greek ῥόδον (rhódon) for “rose”, due to its pinkish color, and ὄψις (ópsis) for “sight”.Sensory rhodopsin IIPhotopigment: Photopigments are unstable pigments that undergo a chemical change when they absorb light. The term is generally applied to the non-protein chromophore moiety of photosensitive chromoproteins, such as the pigments involved in photosynthesis and photoreception.Rhodopsin kinase: Rhodopsin kinase (, cone opsin kinase, G-protein-coupled receptor kinase 1, GPCR kinase 1, GRK1, GRK7, opsin kinase, opsin kinase (phosphorylating), rhodopsin kinase (phosphorylating), RK, STK14) is a serine/threonine-specific protein kinase involved in phototransduction. This enzyme catalyses the following chemical reactionTransducinMelanopsin: Melanopsin is a type of photopigment belonging to a larger family of light-sensitive retinal proteins called opsins and encoded by the gene Opn4. Two other opsins in the mammalian retina are both involved in the formation of visual images: rhodopsin and photopsin in the rod and cone photoreceptor cells, respectively.Grow lightRod cellHalorhodopsin: Halorhodopsin is a light-gated ion pump, specific for chloride ions, found in archaea, known as halobacteria. It is a seven-transmembrane protein of the retinylidene protein family, homologous to the light-driven proton pump bacteriorhodopsin, and similar in tertiary structure (but not primary sequence structure) to vertebrate rhodopsins, the pigments that sense light in the retina.Schiff baseBeef cattle: Beef cattle are cattle raised for meat production (as distinguished from dairy cattle, used for milk production). The meat of adult cattle is known as beef.Neuropathy, ataxia, and retinitis pigmentosaRecoverinRetinal regeneration: Retinal regeneration deals with restoring retinal function to vertebrates so impaired.Graneledone yamana: Graneledone yamana is a species of octopus in the genus Graneledone. G.Bacteriorhodopsin: Bacteriorhodopsin is a protein used by Archaea, most notably by Halobacteria, a class of the Euryarchaeota.See the NCBI webpage on HalobacteriaIt acts as a proton pump; that is, it captures light energy and uses it to move protons across the membrane out of the cell.Protein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.Coles PhillipsSpectrophotometry: In chemistry, spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength.Allen, D.X-linked congenital stationary night blindnessHalobacterium salinarum: Halobacterium salinarum is an extremely halophilic marine Gram-negative obligate aerobic archaeon. Despite its name, this microorganism is not a bacterium, but rather a member of the domain Archaea.Hydroxylamine dehydrogenase: Hydroxylamine dehydrogenase (, HAO (ambiguous)) is an enzyme with system name hydroxylamine:ferricytochrome-c oxidoreductase. This enzyme catalyses the following chemical reactionIsomerization: In chemistry isomerization (also isomerisation) is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms have a different arrangement e.g.Reaction coordinateOpsinDatabase of protein conformational diversity: The Database of protein conformational diversity (PCDB) is a database of diversity of protein tertiary structures within protein domains as determined by X-ray crystallography. Proteins are inherently flexible and this database collects information on this subject for use in molecular research.Transmembrane domain: Transmembrane segment usually denotes a single transmembrane alpha helix of a transmembrane protein, also known as an integral protein.http://www.Burst kinetics: Burst kinetics is a form of enzyme kinetics that refers to an initial high velocity of enzymatic turnover when adding enzyme to substrate. This initial period of high velocity product formation is referred to as the "Burst Phase".Chemical imaging: Chemical imaging (as quantitative – chemical mapping) is the analytical capability to create a visual image of components distribution from simultaneous measurement of spectra and spatial, time information.http://www.Guanylate-binding protein: In molecular biology, the guanylate-binding protein family is a family of GTPases that is induced by interferon (IFN)-gamma. GTPases induced by IFN-gamma (Interferon-inducible GTPase) are key to the protective immunity against microbial and viral pathogens.Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.Halobacterium: In taxonomy, Halobacterium is a genus of the Halobacteriaceae.See the NCBI webpage on Halobacterium.Onykia robusta: Onykia robusta, also known as the robust clubhook squid and often cited by the older name Moroteuthis robusta,Bolstad, K.S.Proton-sensing G protein-coupled receptorsProximity ligation assay: Proximity ligation assay (in situ PLA) is a technology that extends the capabilities of traditional immunoassays to include direct detection of proteins, protein interactions and modifications with high specificity and sensitivity. Protein targets can be readily detected and localized with single molecule resolution and objectively quantified in unmodified cells and tissues.Clinotarsus alticola: Clinotarsus alticola is a species of frog in the Ranidae family. Common names for this species include: Assam Hills frog, Annandale's frog, pointed-headed frog, palebrown stream frog, hill frog, point-nosed frog, and high-altitude frog.
