该基因编码细胞异质核核糖核蛋白（hnrnp）家族的一个成员。hnrnps是一种rna结合蛋白，它与异质核rna（hnrna）复合，调节rna的选择性剪接、多聚腺苷酸化和其他方面的代谢和转运。编码蛋白在mrna成熟的多个方面发挥作用，并与多种多蛋白复合物（包括apob-rna编辑复合物和运动神经元存活复合物）相关。另外，该基因的剪接转录变体编码多个亚型，并且该基因的假基因位于20号染色体的短臂上。[由RefSeq提供，2011年12月]
This gene encodes a member of the cellular heterogeneous nuclear ribonucleoprotein (hnRNP) family. hnRNPs are RNA binding proteins that complex with heterogeneous nuclear RNA (hnRNA) and regulate alternative splicing, polyadenylation, and other aspects of mRNA metabolism and transport. The encoded protein plays a role in multiple aspects of mRNA maturation and is associated with several multiprotein complexes including the apoB RNA editing-complex and survival of motor neurons (SMN) complex. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the short arm of chromosome 20.
