Recombinant Proteins and Enzymes
Offering Industry’s Largest Portfolio of Purified Recombinant Proteins for Screening Inhibitors
Recombinant proteins in drug discovery and development are exogenous proteins expressed in a production organism and used for the treatment or prevention of disease in humans or animals. 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. Epigenetic proteins modify the structure of DNA or its associated proteins, such as histones, in order to regulate gene expression. These proteins play roles in the regulation of intracellular signaling pathways or modulate epigenetic mechanisms. Ubiquitin proteins perform key roles in protein degradation pathways and cellular processes such as DNA repair, gene expression, and endocytosis.
There are ~538 kinases in the human genome (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.
