Heterogeneous nuclear ribonucleoprotein H (HNRNPH1)

This protein is a part of the heterogeneous nuclear ribonucleoprotein (hnRNP) complexes that provide the substrate for the processing events that pre-mRNAs undergo before becoming functional, translatable mRNAs in the cytoplasm. Mediates pre-mRNA alternative splicing regulation.

Inhibits, together with CUGBP1, insulin receptor (IR) pre-mRNA exon 11 inclusion in myoblast. Binds to the IR RNA.
