RPS10(核糖体蛋白S10)是核糖体小亚基的组成蛋白之一,属于RPS基因家族(核糖体蛋白家族),该家族成员普遍参与核糖体组装和蛋白质翻译过程。RPS10在细胞质中与rRNA结合形成40S核糖体亚基,直接参与mRNA解码和蛋白质合成,其功能对维持细胞稳态至关重要。若发生功能丧失突变(如错义突变或缺失),会导致核糖体组装异常,引发核糖体病(如Diamond-Blackfan贫血),表现为造血障碍、先天畸形等。该基因与多种癌症相关,在结直肠癌和肝癌中常出现过表达,可能通过激活PI3K-AKT通路促进肿瘤增殖;而表达降低则导致翻译效率下降,引发p53依赖的细胞凋亡。RPS家族共性包括:高度保守性、多数定位于细胞质、依赖协同调控网络维持表达平衡。过表达时可能破坏核糖体平衡,触发未折叠蛋白反应(UPR);低表达则引发核糖体应激反应,通过RP-MDM2-p53通路抑制细胞周期。需要注意的是,"核糖体病"(ribosomopathy)是近年提出的概念,指核糖体功能异常导致的特定综合征。
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 S10E family of ribosomal proteins. It is located in the cytoplasm. Variable expression of this gene in colorectal cancers compared to adjacent normal tissues has been observed, although no correlation between the level of expression and the severity of the disease has been found. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. Alternate splicing results in multiple transcript variants that encode the same protein. Naturally occurring read-through transcription occurs between this locus and the neighboring locus NUDT3 (nudix (nucleoside diphosphate linked moiety X)-type motif 3).[provided by RefSeq, Feb 2011]
