Which drugs are protein kinase inhibitors?
Protein Kinase Inhibitors
| Drug | Target | Type |
|---|---|---|
| Imatinib | Platelet-derived growth factor receptor beta | target |
| Imatinib | Tyrosine-protein kinase ABL1 | target |
| Imatinib | Mast/stem cell growth factor receptor Kit | target |
| Imatinib | RET proto-oncogene | target |
Are kinase inhibitors proteins?
A protein kinase inhibitor is a type of enzyme inhibitor that blocks the action of one or more protein kinases. Protein kinases are enzymes that add a phosphate (PO4) group to a protein, and can modulate its function….Examples.

What is PLK1 gene?
PLK1 (Polo Like Kinase 1) is a Protein Coding gene. Diseases associated with PLK1 include Gonococcal Keratitis and Cataract 36. Among its related pathways are Activated PKN1 stimulates transcription of AR (androgen receptor) regulated genes KLK2 and KLK3 and Regulation of PLK1 Activity at G2/M Transition.
Are protein kinase inhibitors chemotherapy?
Tyrosine Kinase Inhibitors as Sensitizing Agents for Chemotherapy, the fourth volume in the Cancer Sensitizing Agents for Chemotherapy Series, focuses on strategic combination therapies that involve a variety of tyrosine kinase inhibitors working together to overcome multi-drug resistance in cancer cells.
What is a type II kinase inhibitor?
Type-II kinase inhibitors represent a class of chemicals that trap their target kinases in an inactive, so-called DFG-out, state, occupying a hydrophobic pocket adjacent to the ATP binding site.
How many kinase inhibitors are there?
There are over 100 small-molecule kinase inhibitors active in late stages of clinical development and many more are likely to be approved in the coming years.
What do protein kinase inhibitors do?
A protein kinase inhibitor is a type of enzyme inhibitor that can block the action of protein kinases. Protein kinases add a phosphate group to a protein in a process called phosphorylation, which can turn a protein on or off and therefore affect its level of activity and function.
How is Plk1 activated?
Like many kinases, Plk1 is activated by phosphorylation in its T loop, which induces a conformational change to promote catalysis. Phosphorylation at that site is also thought to lock the protein in an open conformation, where the kinase domain and the PBD are dissociated.
What phosphorylates Plk1?
Plk1 is first recruited to the centrosome in S phase, then appears on the kinetochores in late G2, and at the end of mitosis, it translocates to the central spindle. Activation of Plk1 requires phosphorylation of T210 by Aurora A, an event that critically depends on the co-factor Bora.
Are kinase inhibitors immunotherapy?
A number of recent studies have indicated that antiangiogenic tyrosine kinase inhibitors (TKIs) target multiple components of the tumor microenvironment and are an ideal class of agents for synergizing with cancer immunotherapy.
What is a Type 1 inhibitor?
Type I inhibitors bind to the active protein kinase conformation (DFG-Asp in, αC-helix in). Type V inhibitors bind to two different regions of the protein kinase domain and are therefore bivalent inhibitors. The type I-V inhibitors are reversible. In contrast, type VI inhibitors bind covalently to their target enzyme.
Does kinase use ATP?
This kinase uses an ATP molecule to supply the phosphate to thymidine, as shown below. This transfer of a phosphate from one nucleotide to another by thymidine kinase, as well as other nucleoside and nucleotide kinases, functions to help control the level of each of the different nucleotides.
