RPL22(核糖体蛋白L22)是核糖体60S大亚基的一个组成蛋白,属于RPL基因家族(核糖体蛋白家族),该家族成员均参与核糖体组装及蛋白质翻译过程。RPL22在细胞质中与rRNA结合,帮助维持核糖体结构稳定性,并直接参与mRNA解码和肽链延伸。其表达产物具有典型的碱性氨基酸特征,能与RNA静电结合。该基因的突变可能导致核糖体功能异常,引发翻译效率下降或错误,与钻石-布莱克范贫血(Diamond-Blackfan anemia,一种核糖体病)及部分癌症(如T细胞急性淋巴细胞白血病)相关。研究发现,RPL22缺失会触发p53依赖的细胞周期阻滞,而某些癌症中出现的RPL22移码突变(如外显子4缺失)会导致截短蛋白产生,破坏核糖体质量控制机制。在斑马鱼模型中,RPL22低表达会导致造血缺陷和体型异常。该基因还参与免疫调控,其过表达可能通过影响核糖体通量改变特定mRNA(如GATA1等转录因子)的翻译效率。RPL基因家族的共性包括:高度保守性、多数含RNA结合域、受MYC等癌基因转录调控、部分成员具有核糖体之外的功能(如DNA修复)。需要注意的是,"核糖体蛋白L22"的中文译名存在争议,部分文献沿用英文简称RPL22(Ribosomal Protein L22)。

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 cytoplasmic ribosomal protein that is a component of the 60S subunit. The protein belongs to the L22E family of ribosomal proteins. Its initiating methionine residue is post-translationally removed. The protein can bind specifically to Epstein-Barr virus-encoded RNAs (EBERs) 1 and 2. The mouse protein has been shown to be capable of binding to heparin. Transcript variants utilizing alternative polyA signals exist. As is typical for genes encoding ribosomal proteins, there are multiple processed pseudogenes of this gene dispersed through the genome. It was previously thought that this gene mapped to 3q26 and that it was fused to the acute myeloid leukemia 1 (AML1) gene located at 21q22 in some therapy-related myelodysplastic syndrome patients with 3;21 translocations; however, these fusions actually involve a ribosomal protein L22 pseudogene located at 3q26, and this gene actually maps to 1p36.3-p36.2.
