The HNRNPA1 protein is complexly involved in multiple RNA processing functions, packaging pre-mRNA into hnRNP particles, promoting Poly(A) mRNA transport, and regulating splice site selection. Crucially, it binds inhibitoryly to sequences flanking PKM exon 9, favoring the inclusion of exon 10 in pyruvate kinase PKM splicing, thereby generating the PKM M2 isoform. HNRNPA1 Protein, Human (His) is the recombinant human-derived HNRNPA1 protein, expressed by E. coli , with N-6*His labeled tag.

Human

The HNRNPA1 Protein is intricately involved in various aspects of RNA processing, including the packaging of pre-mRNA into hnRNP particles, transport of poly(A) mRNA from the nucleus to the cytoplasm, and modulation of splice site selection. Notably, it plays a crucial role in the splicing of pyruvate kinase PKM by binding repressively to sequences flanking PKM exon 9, inhibiting exon 9 inclusion and favoring exon 10 inclusion, ultimately leading to the production of the PKM M2 isoform. Furthermore, HNRNPA1 exhibits the ability to bind to the internal ribosome entry site (IRES), thereby inhibiting the translation of the apoptosis protease activating factor APAF1. Additionally, it may bind to specific miRNA hairpins, expanding its role in post-transcriptional gene regulation. Under conditions of microbial infection, HNRNPA1 may also play a role in HCV RNA replication, highlighting its versatility in contributing to various aspects of RNA metabolism and viral processes.
