关于 HNRNPM

功能概要

该基因属于普遍表达的异质核核糖核蛋白 (hnRNP) 亚家族。 hnRNPs 是 RNA 结合蛋白，它们与异质核 RNA (hnRNA) 复合。这些蛋白质与细胞核中的前体 mRNA 相关，并且似乎影响前体 mRNA 加工以及 mRNA 代谢和运输的其他方面。虽然所有的 hnRNP 都存在于细胞核中，但有些似乎在细胞核和细胞质之间穿梭。 hnRNP 蛋白具有独特的核酸结合特性。由该基因编码的蛋白质具有三个重复的与 RNA 结合的准 RRM 结构域。这种蛋白质还构成了 N-乙酰葡糖胺特异性受体的单体，据推测该受体会触发未成熟的 GlcNAc 甲状腺球蛋白分子的选择性再循环。可变剪接导致多个转录本变体。[RefSeq 提供，2011 年 8 月]

This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and Other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene has three repeats of quasi-RRM domains that bind to RNAs. This protein also constitutes a monomer of the N-acetylglucosamine-specific receptor which is postulated to trigger selective recycling of immature GlcNAc-bearing thyroglobulin molecules. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]
