Heterogeneous nuclear ribonucleoprotein F (HNRNPF)

Part of the heterogeneous nuclear ribonucleoprotein (hnRNP) complexes that provide the substrate for the processing events that pre-mRNAs undergo before becoming functional, translatable mRNAs in the cytoplasm. Plays a role in the regulation of alternative splicing events.

Binds G-rich sequences in pre-mRNAs and retains target RNA in an unfolded state. .
