Overview
NCBP1 mediates U snRNA export from the nucleus. Binds to 5' capped mRNA. Found in aU snRNA export complex with RNUXA/PHAX, CBP20, CBP80, RAN, XPO1 and m7G-capped RNA. Interaction with RNUXA/PHAX. Heterodimer with NCBP2. Is part of the exon junction complex (EJC) containing NCBP1, NCBP2, RNPS1, RBM8A, SRRM1, NXF1, UPF3B, UPF2, THOC4 and/or REFBP2. Note: This description may include information from UniProtKB.
