Anti-hnRNP F Antibody, clone 3H4

The hnRNP F protein is member of a subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs).The hnRNPs are RNA binding proteins that complex with heterogeneous nuclear RNA (hnRNA) and associate with pre-mRNAs in the nucleus. These complexes are associated with pre-mRNA processing and other aspects of mRNA metabolism and transport. There are more than 20 different heterogeneous nuclear ribonucleoproteins (hnRNPs) associated with pre-mRNAs in the nucleus of mammalian cells. These different hnRNPs display a range of affinities for a variety of ribonucleotidehomopolymers and ssDNA sequences. In constrast, hnRNP F protein as well as hnRNP H (a highly related protein) appear to bind only to poly(rG). These unique RNA-binding properties, as well as the amino acid sequence and other data showing a distinct intranuclear localization of hnRNP F and hnRNP H suggest they are unique from other hnRNP and play an important role in the processing of RNAs containing guanosine-rich sequences.
