NCBP2, aa1-156, Recombinant, Human (Nuclear Cap-binding Protein Subunit 2, 20kD Nuclear Cap-binding

NCBP2, also known as CBC2, is a component of the nuclear cap-binding protein complex (CBC), which binds to the monomethylated 5' cap of nascent pre-mRNA in the nucleoplasm. This protein has an RNP domain commonly found in RNA binding proteins, and contains the cap-binding activity. The CBC promotes pre-mRNA splicing, 3'-end processing, RNA nuclear export, and nonsense-mediated mRNA decay. Source: Recombinant corresponding to aa1-156 of human NCBP2 protein, fused to His-tag at N-terminus, expressed in E.coli.
