This gene encodes a nuclear protein with an RRM (
RNA recognition motif
RNA recognition motif, RNP-1 is a putative RNA-binding domain of about 90 amino acids that are known to bind single-stranded RNAs. It was found in many eukaryotic proteins.

cleavage stimulation factor (CSTF) complex that is involved in the 3' end cleavage and
polyadenylation
Polyadenylation is the addition of a poly(A) tail to an RNA transcript, typically a messenger RNA (mRNA). The poly(A) tail consists of multiple adenosine monophosphates; in other words, it is a stretch of RNA that has only adenine bases. In eu ...

[ ]BARD1
BRCA1-associated RING domain protein 1 is a protein that in humans is encoded by the ''BARD1'' gene. The human BARD1 protein is 777 amino acids long and contains a RING finger domain (residues 46-90), four ankyrin repeats (residues 420-555), and t ...
BRCA1
Breast cancer type 1 susceptibility protein is a protein that in humans is encoded by the ''BRCA1'' () gene. Orthologs are common in other vertebrate species, whereas invertebrate genomes may encode a more distantly related gene. ''BRCA1'' is a ...
