Overview
-
NCBP2 produced in E. Coli is a single, non-glycosylated polypeptide chain containing 176 amino acids (1-156a.a.) and having a molecular mass of 20.1kDa. NCBP2 is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. NCBP2 is a part of the nuclear cap-binding protein complex (CBC) that binds to the monomethylated 5'' cap of nascent pre-mRNA in the nucleoplasm. NCBP2 protein has an RNP domain usually located in RNA binding proteins, and contains the cap-binding activity. CBC promotes pre-mRNA splicing, 3''-end processing, RNA nuclear export, and nonsense-mediated mRNA decay.
