Crystallin gene
WebBeta-crystallin B2 is a protein that in humans is encoded by the CRYBB2 gene.. Function. Crystallins are separated into two classes: taxon-specific, or enzyme, and ubiquitous. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. Since lens central fiber cells lose their … WebCrystallins are the most prevalent proteins in the lens. Comprising two families, α- and βγ-crystallins, they make up 90% of water-soluble proteins of the mammalian lens.178 …

WebFeb 4, 1997 · Three classes of crystallins are present in vertebrate lenses: α, β, and γ. α-Crystallins compose up to 50% of the total protein mass of the mammalian lens and are isolated under physiologic conditions as a high-molecular mass aggregate of ≈800,000 Da ().There are two different α-crystallin polypeptides, αA-crystallin (αA) and αB-crystallin … WebBeta-crystallin A3 is a protein that in humans is encoded by the CRYBA1 gene. ... This gene, a beta acidic group member, encodes two proteins (crystallin, beta A3 and crystallin, beta A1) from a single mRNA, the latter protein is 17 aa shorter than crystallin, beta A3 and is generated by use of an alternate translation initiation site. ...
WebThe putative proteins encoded by these genes contained a typical α-crystallin domain. The expression patterns of these genes during different developmental stages, in various tissues of male and female adults, as well as in response to extreme temperatures and UV-A stress were studied via real-time quantitative polymerase chain reaction. WebMar 13, 2016 · Liver cells do not have the STFs to activate the crystallin gene, and lens cells cannot activate the album gene. However, my book also tells me that there is a basal level of transcription that arises from the binding of general transcription factors. Enhancers only increase the rate of transcription on top of that basal rate.

WebThe importance of alpha-crystallins in the maintenance of lens transparency was demonstrated by the work of Brady et al. (1997), who showed that mice homozygous for a targeted disruption of the alpha-A-crystallin gene developed cataracts and had cytoplasmic inclusion bodies containing the small heat-shock protein alpha-B-crystallin (123590).
