Protein Kinase Inhibitor Development for Ovarian Cancer
Protein kinases regulate a variety of cellular functions, including growth, division, metabolism, and apoptosis, through phosphorylation during cellular signaling. Alfa Cytology possesses extensive experience in studying protein kinase inhibitors and is well-equipped to conduct comprehensive research in this area, employing advanced techniques and methodologies to identify and characterize novel therapeutic targets.
Overview of Protein Kinase
Protein kinases are enzymes that phosphorylate other proteins by adding phosphate groups, typically to serine, threonine, or tyrosine residues. This process regulates key cellular functions, including cell growth, division, metabolism, and apoptosis. By phosphorylating transcription factors and proteins involved in transcription, protein kinases control gene expression and various cellular signaling pathways.

Classification of Protein Kinases
Protein kinases are categorized based on the specific residues they phosphorylate, which is pivotal in defining their function and targets within the ovarian cancer cell.
Serine/Threonine Kinases
These kinases target the hydroxyl group of serine or threonine residues. They are involved in a wide array of ovarian cancer cellular activities, including the regulation of the cell cycle, cell differentiation, and apoptosis.
Tyrosine Kinases
These kinases specifically phosphorylate the hydroxyl group of tyrosine residues. They play an essential role in signal transduction pathways, mediating the control of diverse ovarian cancer cellular processes such as cell division, growth, and metabolism.
Dual-Specificity Kinases
Unique among protein kinases, dual-specificity kinases have the ability to phosphorylate both serine/threonine and tyrosine residues. This dual capability allows them to function as critical regulators in complex ovarian cancer cellular signaling networks.
Our Services
The Alfa Cytology team is diligently working on the development of novel inhibitors targeting specific protein kinases.
