MeSH Heading: Retinal Pigments
Tree Number(s): D23.767.930
Unique ID: D012168
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D012168
Annotation: not for deposition of pigments in the retina (= RETINITIS PIGMENTOSA)
Scope Note: Photosensitive protein complexes of varied light absorption properties which are expressed in the PHOTORECEPTOR CELLS. They are OPSINS conjugated with VITAMIN A-based chromophores. Chromophores capture photons of light, leading to the activation of opsins and a biochemical cascade that ultimately excites the photoreceptor cells.
Entry Term(s): Retinal Photoreceptor Pigment; Retinal Photoreceptor Pigments; Retinal Pigment; Visual Pigment; Visual Pigments
NLM Classification #: WW 270
Date Established: 1966/01/01
Date of Entry: 1999/01/01
Revision Date: 2020/05/27
