Gene Information

human ... CSTF3(1479)

General description

Cleavage stimulatory factor (CstF3), also called CSTF-77, is a component of CstF heterotrimer. It has a proline-rich domain and the gene is mapped to human chromosome 11p13. CstF3 contains 12 half-A-TPR (HAT) repeats followed by a proline-rich segment.

Specificity

Anti-CSTF3 (N-terminal) specifically recognizes human CSTF3 (also known as Cleavage stimulation factor 77, CSTF-77, CF-1 77 kDa subunit).

Application

Anti-CSTF3 (N-terminal) antibody produced in rabbit has been used in chromatin immunoprecipitation and immunoblotting.

Biochem/physiol Actions

Cleavage stimulatory factor (CstF3) is required for proper 3′-end cleavage and is critical for the assembly of the CstF complex, bridging both CSTF1 and CSTF2. CSTF3 also interacts directly with the RNA polymerase II C-terminal domain (CTD), but with lower efficiency than CSTF1.

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

Store at –20 °C. For continuous use, the product may be stored at 2–8 °C for up to one month. For extended storage, freeze in working aliquots at –20 °C. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

3' end formation of pre-mRNAs is coupled to their transcription via the C-terminal domain (CTD) of RNA polymerase II (Pol II). Nearly all protein-coding transcripts are matured by cleavage and polyadenylation (CPA), which is frequently misregulated in disease. Understanding how
3? end formation of pre-mRNA and phosphorylation of Ser2 on the RNA polymerase II CTD are reciprocally coupled in human cells
