a heterogeneous nuclear ribonucleoprotein (hnRNP). One of the major pre-mRNA-binding proteins. Binds tenaciously to poly(C) sequences. Likely to play a role in the nuclear metabolism of hnRNAs, particularly for pre-mRNAs that contain cytidine-rich sequences. Can also bind poly(C) single-stranded DNA. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
