基因检测报告英文版基因简介
Mammalian lens crystallins are divided into alpha, beta, and gamma families. Alpha crystallins are composed of two gene products: alpha-A and alpha-B, for acidic and basic, respectively. Alpha crystallins can be induced by heat shock and are members of the small heat shock protein (HSP20) family. They act as molecular chaperones although they do not renature proteins and release them in the fashion of a true chaperone; instead they hold them in large soluble aggregates. These heterogeneous aggregates consist of 30-40 subunits; the alpha-A and alpha-B subunits have a 3:1 ratio, respectively. Two additional functions of alpha crystallins are an autokinase activity and participation in the intracellular architecture. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. Alpha-A and alpha-B gene products are differentially expressed; alpha-A is preferentially restricted to the lens and alpha-B is expressed widely in many tissues and organs. Elevated expression of alpha-B crystallin occurs in many neurological diseases; a missense mutation cosegregated in a family with a desmin-related myopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2019]
基因突变所影响的基因信息
哺乳动物晶状体晶体蛋白分为α,β和γ家族。α晶状蛋白由两种基因产物组成:分别为酸性和碱性的α-A和α-B。α晶状蛋白可以通过热激诱导,并且是小热激蛋白(HSP20)家族的成员。它们起分子伴侣的作用,尽管它们不复性蛋白质并以真正的伴侣形式释放它们。取而代之的是,它们将它们容纳在大的可溶性聚集物中。这些异质聚集体由30-40个亚基组成;α-A和α-B亚基的比例分别为3:1。α晶状蛋白的两个附加功能是自身激酶活性和参与细胞内结构。基于其执行机械上不同功能的能力,已将编码的蛋白鉴定为月光蛋白。Alpha-A和alು
