Monoclonal Anti-hnRNP-C1/C2 (mouse IgG1isotype) is derived from the 4F4 hybridoma produced by the fusion of mouse myeloma cells (SP2/0 cells) and splenocytes from BALB/c mice immunized with RNPs eluted from oligo (dT) cellulose column. Heterogeneous nuclear ribonucleoproteins C1/C2 (HnRNP C1/C2) are synthesized from C2 protein by alternative splicing and have an additional13-amino-acids. It is localized in nucleus and has leucine zipper-like RNA-binding motif. The hnRNP-C proteins have a single ribonucleoprotein (RNP) motif RNA-binding domain (RBD) of 80 to 100 amino acid long.
Heterogeneous nuclear ribonucleoproteins C1/C2(HnRNP C1/C2) is involved in protein translation, mRNA biogenesis and transport. The hnRNP-C proteins preferentially bind to uridine-rich RNA sequences. Oligomerization of the protein through leucine rich regions in its C-terminal end is important for RNA binding. Mutation of the hnRNPC gene is implicated in embryonic lethal phenotype.
