ANTI-CSTF1 (C-TERMINAL) ANTIBODY PRODUCED IN RABBIT AFFINITY ISOLATED ANTIBODY

General description

Cleavage stimulation factor 1 (CSTF1) contains seven WD-40 repeats. The CSTF1 gene is mapped to human chromosome 20q13.2-q13.31.

Specificity

Anti-CSTF1 (C-terminal) specifically recognizes human CSTF1 (also known as Cleavage stimulation factor).

Application

Anti-CSTF1 (C-terminal) antibody produced in rabbit is suitable for immunoprecipitation at a working amount of 5-10μg using K562 lysates and western blotting at a concentration of 2-4μg/mL using K562 lysates.

Biochem/physiol Actions

CSTF1 is required for in vitro cleavage activity. The WD-40 repeats are crucial for the interaction with CSTF3. CSTF1 also interacts directly with the RNA polymerase II CTD, suggesting a role in linking transcription and mRNA 3′-ends processing.

Cleavage stimulation factor (50kDa) subunit is a protein encoded by the CSTF1 gene in humans. It is one of the multiple factors that plays a significant role during polyadenylation of mammalian pre-mRNAs. The mRNA polyadenylation factor CstF interacts with the BRCA1-associated protein BARD1 resulting in repression of the nuclear mRNA polyadenylation machinery. It participates in the regulation of endogenous transcripts during DNA-damage.

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.
