Anti-hnRNP-A2/B1: Monoclonal hnRNP-A2/B1 Antibody

BACKGROUND The heterogeneous nuclear ribonucleoproteins (hnRNPs) are a large family of nucleic acid binding proteins that are often found in, but not restricted to, the 40S-ribonucleoprotein particle. Subsets of hnRNPs are strictly nuclear while others shuttle between the nucleus and cytoplasm.1 hnRNP complexes are also major constituents of the spliceosome. They are composed of approximately 30 different proteins, which can bind to nascent pre-mRNA. Members of the hnRNP family have been implicated in many aspects of mRNA maturation/turnover, and in telomere and telomerase regulation. Among these, the hnRNP-A/B proteins form a subgroup of highly related proteins consisting of two adjacent RNA binding domains (RBD) within the N-terminal parts, whereas the C-terminal halves contain almost 50% glycine residues.2 hnRNP A2/B1 has been found overexpressed in the early stages of lung and other cancers.3,4 Thus, hnRNP-A2/B1 can be a marker of carcinogenesis.
