Product Pathways - Motif Antibodies
Phospho-(Ser/Thr) CK2 Substrate (P-S/T3-100) Rabbit mAb #8738
Reactivity Key: All=All species expected
Species cross-reactivity is determined by western blot.
Specificity / Sensitivity
Phospho-(Ser/Thr) CK2 Substrate (P-S/T3-100) Rabbit mAb recognizes endogenous proteins containing a pS/pTDXE motif, which is a CK2 phosphorylation consensus sequence. This antibody is a useful tool to study CK2 substrates.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide containing the T*DXE motif.
Western blot analysis of extracts from HeLa cells, untreated or treated with Calyculin A #9902 (10 nM, 30 min) or Staurosporine #9953 (1 μM, 3 hr), using Phospho-(Ser/Thr) CK2 Substrate (P-S/T3-100) Rabbit mAb.
Western blot analysis of extracts from HeLa cells, transfected with SignalSilence® Control siRNA (Unconjugated) #6568 (-) or SignalSilence® CK2α siRNA I #6389 (+), using Phospho-(Ser/Thr) CK2 Substrate (P-S/T3-100) Rabbit mAb (upper), CK2α Antibody #2656 (middle), or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower).
Casein Kinase II (CK2) is a highly conserved, ubiquitously expressed, and constitutively active tetrameric Ser/Thr protein kinase with hundreds of substrates participating in the regulation of a variety of cellular processes including cell cycle progression, apoptosis, transcription, inflammation, and the DNA damage response. Research studies have implicated CK2 in roles related to viral infection, cancer, and other diseases (1-5). CK2 substrates contain multiple acidic residues (Asp and Glu) located downstream of the phosphorylated Ser or Thr residue. The consensus sequence for CK2 substrates is pS/pTD/EXD/E with the most crucial residue at the +3 position followed by the residue at the +1 position (6).
