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.

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.
