NIH3T3 fibroblast lysates, spiked with 1 ng active GST tagged-TTK protein [Invitrogen, Prod # PV3792] (2-6) or Kinase dead mutant TTK protein (1) were resolved on a 10% polyacrylamide gel and transferred to PVDF. The membrane was blocked with a 3% BSA-TBST buffer for one hour at room temperature, and then incubated with the TTK [pTpS33/37] antibody for two hours at room temperature in 3% BSA-TBST buffer, following prior incubation with: no peptide (2), the non-phosphopeptide corresponding to the phosphopeptide immunogen (3), a generic phosphothreonine-containing peptide (4), a generic phosphoserine (5), or the phosphopeptide immunogen corresponding to TTK [pTpS33/37] (6). After washing, the membrane was incubated with goat F (ab')2 anti-rabbit IgG HRP conjugate (Prod # ALI4404) and signals were detected using the Pierce SuperSignal™ reagent. The data show that the signal detected in the active TTK protein was selectively blocked by the phosphopeptide corresponding to TTK [pTpS33/37]. The data also show the loss of phosphorylation signal on kinase dead protein indicating that the signal is phosphorylation site-specific.

Protein kinases are enzymes that transfer a phosphate group from a phosphate donor, generally the g phosphate of ATP, onto an acceptor amino acid in a substrate protein. By this basic mechanism, protein kinases mediate most of the signal transduction in eukaryotic cells, regulating cellular metabolism, transcription, cell cycle progression, cytoskeletal rearrangement and cell movement, apoptosis, and differentiation. With more than 500 gene products, the protein kinase family is one of the largest families of proteins in eukaryotes. The family has been classified in 8 major groups based on sequence comparison of their tyrosine (PTK) or serine/threonine (STK) kinase catalytic domains. The STE group (homologs of yeast Sterile 7, 11, 20 kinases) consists of 50 kinases related to the mitogen-activated protein kinase (MAPK) cascade families (Ste7/MAP2K, Ste11/MAP3K, and Ste20/MAP4K). MAP kinase cascades, consisting of a MAPK and one or more upstream regulatory kinases (MAPKKs) have been best characterized in the yeast pheromone response pathway. Pheromones bind to Ste cell surface receptors and activate yeast MAPK pathway.
