Recombinant Kinase & Phosphatase Enzymes

Largest Portfolio of Purified Recombinant Proteins for Screening Inhibitors

Kinases are cell signaling enzymes that catalyze the transfer of a phosphate group from ATP to its substrate, while phosphatases are regulatory enzymes that remove the phosphate group. Both enzyme families play roles in the regulation of intracellular signaling pathways. There are ~535 kinases in the human kinome (eLife Sciences, 2021), and they are generally grouped into either serine/threonine, tyrosine, or lipid kinases. Kinase substrates include a variety of intracellular proteins and molecules, including other kinases, transcription factors, lipids, and other proteins. The phosphorylation and dephosphorylation of the substrate modifies its enzymatic activity. These activities include diverse cellular processes, including cell division, protein synthesis, transcriptional regulation, and neurotransmission. Activating mutations of kinases, or their dysregulation by upstream factors, that lead to either gain-of-function or loss-of-function are implicated in many diseases, including cancer.

 

Eurofins DiscoverX provides a new home for the original Millipore (Upstate) kinase enzyme portfolio covering over 70% of the kinome.
