This gene belongs to the subfamily of ubiquitously expressed
heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are nucleic acid binding proteins and they complex with
heterogeneous nuclear RNA (hnRNA). The interaction sites on the RNA are frequently biased towards particular sequence motifs. 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. It localizes to both the nucleus and the cytoplasm. This protein is implicated in the regulation of mRNA stability. == Interactions ==
