The hnRNPs are RNA binding proteins that complex with heterogeneous nuclear RNA (hnRNA) and associate with pre-mRNAs in the nucleus. These complexes are associated with pre-mRNA processing and other aspects of mRNA metabolism and transport. While all hnRNPs are present in the nucleus, data suggests they shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by hnRNP A2/B1 belongs to the A/B subfamily of ubiquitously express hnRNPs. This family member has two repeats of quasi-RRM domains that bind to RNAs. Two alternatively spliced transcript variants which encode different isoforms have been described. In autoimmune diseases such as rheumatoid arthritis, systemic lupus erythematosus, and mixed connective tissue disease hnRNPA2B1 can serve as an autoantigen. Although this protein is predominantly nucleoplasmic, in some tissues isoform A2 is found in the cytoplasm.

This gene belongs to the A/B 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 two repeats of quasi-RRM domains that bind to RNAs. This gene has been described to generate two alternatively spliced transcript variants which encode different isoforms. [provided by RefSeq].
