ZNF239 belongs to the krueppel C2H2-type zinc-finger protein family. It contains 9 C2H2-type zinc fingers. ZNF239 may be involved in transcriptional regulation.MOK2 proteins are DNA- and RNA-binding proteins that are mainly associated with nuclear RNP components, including the nucleoli and extranucleolar structures (Arranz et al., 1997 [PubMed 9121460]).[supplied by OMIM].
