Synthetic peptide corresponding to residues near the carboxy terminus of human hnRNP Q.

Heterogeneous nuclear ribonucleoprotein Q and R belong to a family of hnRNP proteins that are involved in RNA binding, RNA biosynthesis and mRNA transport from nucleus to cytoplasm (1-3). These two proteins are encoded by different gene but have 83% homology. hnRNP
Q has three alternative splice variants (hnRNP Q1-3) (1-3). Methylation of carboxy-terminal arginine residues is required for nuclear localization (4). hnRNP Q binds to AUrich mRNA in conjunction with AUF1 and regulates mRNA decay (5). hnRNP Q isoforms play a crucial role in mediating nuclear function of survival of motor neuron (SMN) complex (6, 7) and modulate RNA biosynthesis and hepatitis C virus replication (8). hnRNP R was identified recently and its function is still under investigation (9), however hnRNP R does not duplicate the biological function of hnRNP Q. Both hnRNP Q and R are present in cytoplasmic mRNP granules containing untranslated mRNAs (10) and both interact with SMN (11).
