Protocol Id: 10
This protocol is intended for immunoprecipitation of native proteins utilizing Protein A agarose beads for analysis by western immunoblot or kinase activity.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
10X Cell Lysis Buffer: (#9803) To prepare 10 ml of 1X cell lysis buffer, add 1 ml cell lysis buffer to 9 ml dH2O, mix.
NOTE: Add 1 mM PMSF (#8553) immediately prior to use.
Proceed to one of the following specific set of steps.
NOTE: To minimize masking caused by denatured IgG heavy chains (~50 kDa), we recommend using Mouse Anti-Rabbit IgG (Light-Chain Specific) (L57A3) mAb (#3677) or Mouse Anti-Rabbit IgG (Conformation Specific) (L27A9) mAb (#3678) (or HRP conjugate #5127). To minimize masking caused by denatured IgG light chains (~25 kDa), we recommend using Mouse Anti-Rabbit IgG (Conformation Specific) (L27A9) mAb (#3678) (or HRP conjugate #5127).

CPSF6 (E4F5F) Rabbit mAb recognizes endogenous levels of total CPSF6 protein.
Human, Mouse, Rat, Monkey
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu56 of human CPSF6 protein.
Cleavage and polyadenylation of pre-mRNA is regulated by a core group of proteins called the cleavage and polyadenylation specificity factors (CPSF) (1,2). The CPSF proteins interact with poly(A) polymerase (PAP) to recognize the AAUAAA sequence motif and add poly(A). CPSF can also interact with downstream cleavage factors to precisely cleave the 3’ end of pre-mRNA (2,3). CPSF is brought to 3’ ends by the carboxy-terminal domain of the Rpb1 subunit of the RNA Polymerase II complex, where it dissociates and initiates polyadenylation (4). CPSF has been shown to have numerous interactions with viral proteins. The influenza NS1 viral protein binds to CPSF4 to prevent 3’ end processing of viral RNAs, inhibiting nuclear export (5).
CPSF6 is a 68 kDa member of the CPSF group that has been shown to target the HIV-1 viral capsid (CA) (6). A truncated form of CPSF6, CPSF6-358, localizes exclusively in the cytoplasm and can oligomerize to bind CA, restricting HIV infection and nuclear entry (7,8).
