Evolution of the Protein Kinase Family Michael Gribskov DEPARTMENT OF BIOLOGICAL SCIENCES
Protein Kinase Protein Protein - P Protein Phosphatase
Are Kinases PhosphoComputers? • multiple sites = AND or OR calculators X P P P OR P P AND X P
Kinase Roles • Protein kinases play essential roles in eukaryotic cells • Regulation of cell cycle, including structural elements • Regulation of enzymes • "signal transducer" • response to environment • response to injury/disease/infection • signal receiver
Signaling Cascades
Protein Kinases • Ser-Thr-Tyr Kinases are common to Eukaryotes (ePK) • Two component Systems (Histidine Kinases) • Bacteria (HK >epK) • Archaea (HK >ePK) • Fungi (ePK > HK) • Animals (ePK > HK) • Plants (ePK > HK)
Archael ePKs Kennelly, P.J., (2003) Biochem. J. 379-389
Bacterial ePKs • ePK? • Pkn family • ABC1 family • RIO
Core Protein Kinases • Ubiquitous • No extra domains • Paradigms: CK1, MAPK • cell cycle • meiosis/mitosis • circadian cycle
Complex Kinases • AGC family • CAMK family • Second messenger regulated • Interact with regulatory subunits • Frequently become fused
Protein Kinase Superfamily DD cAMP cAMP Regulatory Subunit PKA PKC PKG PKB cdk2 src EGFR Catalytic Subunit C1 C2 DD cGMP cGMP PH SH3 SH2 EGF Binding Domain Kinase Core
Kinase Roles • Protein kinases play essential roles in eukaryotic cells • Regulation of cell cycle, including structural elements • Regulation of enzymes • "signal transducer" • response to environment • response to injury/disease/infection • signal receiver
Some Receptor Kinases (EGF receptor) (Insulin receptor) (FGF receptor)
Receptor Kinases • Tyr-kinase in animals • Ser-Thr in plants • His in fungi and bacteria • Clearly the last role to evolve
