Sorafenib is a protein kinase inhibitor with activity against many protein kinases, including VEGFR, PDGFR and RAF kinases. [4] [5] Of the RAF kinases, sorafenib is more selective for c-Raf than B-RAF. [6] (See BRAF (gene)#Sorafenib for details the drug's interaction with B-Raf.) Sorafenib treatment induces autophagy, [7] which may suppress ...
RAF is an acronym for Rapidly Accelerated Fibrosarcoma. [12] RAF kinases participate in the RAS-RAF-MEK-ERK signal transduction cascade, also referred to as the mitogen-activated protein kinase (MAPK) cascade. [11] Activation of RAF kinases requires interaction with RAS-GTPases. The three RAF kinase family members are: A-RAF; B-RAF; c-Raf
The Raf kinase inhibitor protein (RKIP) is a kinase inhibitor protein, that regulates many signaling pathways within the cell. [1] RKIP is a member of the phosphatidylethanolamine-binding protein family and has displayed disruptive regulation on the Raf-1-MEK1/2, ERK1/2 and NF-kappaB signalling pathways, by interaction with the Raf-1 kinase.
Mechanism of action: protein kinase inhibitor: External links; PDB ligand id: 032: ... It is an inhibitor of the B-Raf enzyme and was developed by Plexxikon. [2]
The RAF kinase phosphorylates and activates a MAPK/ERK Kinase (MEK1 or MEK2). The MEK phosphorylates and activates a mitogen-activated protein kinase (MAPK). RAF and MAPK/ERK are both serine/threonine-specific protein kinases. MEK is a serine/tyrosine/threonine kinase. In a technical sense, RAF, MEK, and MAPK are all mitogen-activated kinases ...
RAF proto-oncogene serine/threonine-protein kinase, also known as proto-oncogene c-RAF or simply c-Raf or even Raf-1, is an enzyme [4] that in humans is encoded by the RAF1 gene. [ 5 ] [ 6 ] The c-Raf protein is part of the ERK1/2 pathway as a MAP kinase (MAP3K) that functions downstream of the Ras subfamily of membrane associated GTPases. [ 7 ]
A protein kinase inhibitor (PKI) is a type of enzyme inhibitor that blocks the action of one or more protein kinases. [1] Protein kinases are enzymes that phosphorylate (add a phosphate, or PO 4, group) to a protein and can modulate its function. [2] The phosphate groups are usually added to serine, threonine, or tyrosine amino acids on the ...
B-Raf is a 766-amino acid, regulated signal transduction serine/threonine-specific protein kinase.Broadly speaking, it is composed of three conserved domains characteristic of the Raf kinase family: conserved region 1 (CR1), a Ras-GTP-binding [11] self-regulatory domain, conserved region 2 (CR2), a serine-rich hinge region, and conserved region 3 (CR3), a catalytic protein kinase domain that ...
