RPS19

核糖体是催化蛋白质合成的细胞器，由一个小的40s亚基和一个大的60s亚基组成。这些亚基由4种RNA和大约80种结构上不同的蛋白质组成。这个基因编码一个核糖体蛋白，它是40S亚单位的一个组成部分该蛋白属于核糖体蛋白S19E家族它位于细胞质中。该基因突变导致钻石黑扇贫血（DBA），一种以缺乏或减少红细胞前体为特征的体质性红细胞减少症，见于一部分患者这表明该基因除了具有核糖体功能外，还可能在红细胞的分化和增殖中具有额外的核糖体功能在一些原发性结肠癌中，该基因的表达水平高于正常结肠组织作为编码核糖体蛋白的典型基因，有多个经过处理的假基因散布在基因组中。[由RefSeq提供，2008年7月]
Ribosomes, the organelles that catalyze protein synthesis, consist of a small 40S subunit and a large 60S subunit. Together these subunits are composed of 4 RNA species and approximately 80 structurally distinct proteins. This gene encodes a ribosomal protein that is a component of the 40S subunit. The protein belongs to the S19E family of ribosomal proteins. It is located in the cytoplasm. Mutations in this gene cause Diamond-Blackfan anemia (DBA), a constitutional erythroblastopenia characterized by absent or decreased erythroid precursors, in a subset of patients. This suggests a possible extra-ribosomal function for this gene in erythropoietic differentiation and proliferation, in addition to its ribosomal function. Higher expression levels of this gene in some primary colon carcinomas compared to matched normal colon tissues has been observed. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. [provided by RefSeq, Jul 2008]
