Q9BQ70

功能描述

核糖体质量控制复合物(RQC)的组分,这是一种核糖体相关复合物,介导未完全合成的新生肽链的泛素化和提取以进行蛋白酶体降解 (PubMed:30244831)。在RQC复合物中,是LTN1对未完全合成的蛋白质进行泛素化过程中促进'Lys-48'连接的多泛素链形成所必需的 (PubMed:30244831)。可能通过抑制转录因子NFATC4的活性来负向调节钙调神经磷酸酶-NFAT信号级联反应 (By similarity)。可能在细胞死亡控制中发挥作用 (By similarity)。 {ECO:0000250|UniProtKB:A0A8I6ASZ5, ECO:0000250|UniProtKB:Q8R3L2, ECO:0000269|PubMed:30244831}。

组织特异性

In the embryo, widely expressed with highest levels in brain (PubMed:16574069). In the adult, highest expression is found in the heart (PubMed:16574069, PubMed:32805187). Repressed in cardiac tissue of patients with heart failure (at protein level) (PubMed:32805187). mRNA levels in the heart are unchanged in patients with heart failure (PubMed:32805187).
