NCBP1 - nuclear cap binding protein subunit 1 Gene

Also Known as NCBP; Sto1; CBP80

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 4686

About NCBP1

Cytogenetic location: 9q22.33 Genomic coordinates (GRCh38): 9:97,633,821-97,673,748 (from NCBI)

This gene has 5 transcripts (splice variants) and 210 orthologues. Ubiquitous expression in testis (RPKM 9.3), lymph node (RPKM 7.9) and 25 other tissues.

Summary

The product of this gene 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. The encoded protein promotes high-affinity mRNA-cap binding and associates with the CTD of RNA polymerase II. The CBC promotes pre-mRNA splicing, 3'-end processing, RNA nuclear export, and nonsense-mediated mRNA decay. [provided by RefSeq, Jul 2008]
