This protein is a component of the heterogeneous nuclear ribonucleoprotein (hnRNP) complexes which provide the substrate for the processing events that pre-mRNAs undergo before becoming functional, translatable mRNAs in the cytoplasm. Binds poly(RG). Component of a ribonucleoprotein complex containing mRNAs and RNA-binding proteins including DDX5, HNRNPH2 and SRSF1 as well as splicing regulator ARVCF (PubMed:24644279). Interacts with TXNL4/DIM1 (PubMed:11054566). Expressed ubiquitously. The disease is caused by variants affecting the gene represented in this entry.
