extensive maturational processing, including cleavage and
polyadenylation at the 3-prime end. CPSF3 encodes the 73-kD subunit
of the cleavage and polyadenylation specificity factor (CPSF) and
is the pre-mRNA 3-prime-end-processing endonuclease (Mandel et al.,
2006 [PubMed 17128255]).

NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the metallo-beta-lactamase family. The encoded protein is a 73kDa subunit of the cleavage and polyadenylation specificity factor and functions as an endonuclease that recognizes the pre-mRNA 3'-cleavage site AAUAAA prior to polyadenylation. It also cleaves after the pre-mRNA sequence ACCCA during histone 3'-end pre-mRNA processing. [provided by RefSeq, Oct 2012]
Uniprot Description
CPSF3: Component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. Has endonuclease activity, and functions as mRNA 3'-end-processing endonuclease. Also involved in the histone 3'-end pre-mRNA processing. U7 snRNP- dependent protein that induces both the 3'-endoribonucleolytic cleavage of histone pre-mRNAs and acts as a 5' to 3' exonuclease for degrading the subsequent downstream cleavage product (DCP) of mature histone mRNAs. Cleavage occurs after the 5'-ACCCA-3' sequence in the histone pre-mRNA leaving a 3'hydroxyl group on the upstream fragment containing the stem loop (SL) and 5' phosphate on the downstream cleavage product (DCP) starting with CU nucleotides. The U7-dependent 5' to 3' exonuclease activity is processive and degrades the DCP RNA substrate even after complete removal of the U7-binding site. Binds to the downstream cleavage product (DCP) of histone pre-mRNAs and the cleaved DCP RNA substrate in a U7 snRNP dependent manner. Belongs to the metallo-beta-lactamase superfamily. RNA-metabolizing metallo-beta-lactamase-like family. CPSF3 subfamily.

Product Notes
The CPSF3 cpsf3 (Catalog #AAA9209984) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 192-221. The CPSF3 Antibody (Center) reacts with Human (Predicted Reactivity: Bovine, Mouse) and may cross-react with other species as described in the data sheet. AAA Biotech's CPSF3 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), ELISA (EIA). WB~~1:1000. Researchers should empirically determine the suitability of the CPSF3 cpsf3 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "CPSF3, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
