基因檢測報告英文版基因簡介
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]
基因突變所影響的基因信息
哺乳動物晶狀體晶體蛋白分為α,β和γ家族。α晶狀蛋白由兩種基因產(chǎn)物組成:分別為酸性和堿性的α-A和α-B。α晶狀蛋白可以通過熱激誘導(dǎo),并且是小熱激蛋白(HSP20)家族的成員。它們起分子伴侶的作用,盡管它們不復(fù)性蛋白質(zhì)并以真正的伴侶形式釋放它們。取而代之的是,它們將它們?nèi)菁{在大的可溶性聚集物中。這些異質(zhì)聚集體由30-40個亞基組成;α-A和α-B亞基的比例分別為3:1。α晶狀蛋白的兩個附加功能是自身激酶活性和參與細(xì)胞內(nèi)結(jié)構(gòu)?;谄鋱?zhí)行機(jī)械上不同功能的能力,已將編碼的蛋白鑒定為月光蛋白。Alpha-A和al??
