MAP Kinase Kinase Kinase
Mitogen Activated Protein (MAP) kinase kinase kinase, MAPKKK (or MAP3K) is a serine/threonine-specific protein kinase which acts upon MAP kinase kinase. Subsequently, MAP kinase kinase activates MAP kinase. Several types of MAPKKK can exist but are mainly characterized by the MAP kinases they activate. MAPKKKs are stimulated by a large range of stimuli, primarily environmental and intracellular stressors. MAPKKK is responsible for various cell functions such as cell proliferation, cell differentiation, and apoptosis. The duration and intensity of signals determine which pathway ensues. Additionally, the use of protein scaffolds helps to place the MAPKKK in close proximity with its substrate to allow for a reaction. Lastly, because MAPKKK is involved in a series of several pathways, it has been used as a therapeutic target for cancer, amyloidosis, and neurodegenerative diseases. In humans, there are at least 19 genes which encode MAP kinase kinase kinases: * MAP3K1 (aka MEKK1) * M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serine/threonine-specific Protein Kinase
A serine/threonine protein kinase () is a kinase enzyme, in particular a protein kinase, that phosphorylates the OH group of the amino-acid residues serine or threonine, which have similar side chains. At least 350 of the 500+ human protein kinases are serine/threonine kinases (STK). In enzymology, the term ''serine/threonine protein kinase'' describes a class of enzymes in the family of transferases, that transfer phosphates to the oxygen atom of a serine or threonine side chain in proteins. This process is called phosphorylation. Protein phosphorylation in particular plays a significant role in a wide range of cellular processes and is a very important posttranslational modification. The chemical reaction performed by these enzymes can be written as :ATP + a protein \rightleftharpoons ADP + a phosphoprotein Thus, the two substrates of this enzyme are ATP and a protein, whereas its two products are ADP and phosphoprotein. The systematic name of this enzyme class is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MAP3K10
Mitogen-activated protein kinase kinase kinase 10 is an enzyme that in humans is encoded by the ''MAP3K10'' gene. Function The protein encoded by this gene is a member of the serine/threonine kinase family. This kinase has been shown to activate MAPK8/JNK and MKK4/SEK1, and this kinase itself can be phosphorylated, and thus activated by JNK kinases. This kinase functions preferentially on the JNK signaling pathway, and is reported to be involved in nerve growth factor (NGF) induced neuronal apoptosis. Interactions MAP3K10 has been shown to interact with: * CDC42, * Huntingtin, * KIF3A, * MAPK8IP1, * MAPK8IP2, and * NEUROD1 Neurogenic differentiation 1 (Neurod1), also called β2, is a transcription factor of the NeuroD-type. It is encoded by the human gene NEUROD1. In mice, ''Neurod1'' expression is first seen at embryonic day 12 (E12). It is a member of the Neurod ....

BRAF (gene)
BRAF is a human gene that encodes a protein called B-Raf. The gene is also referred to as proto-oncogene B-Raf and v-Raf murine sarcoma viral oncogene homolog B, while the protein is more formally known as serine/threonine-protein kinase B-Raf. The B-Raf protein is involved in sending signals inside cells which are involved in directing cell growth. In 2002, it was shown to be mutated in some human cancers. Certain other inherited ''BRAF'' mutations cause birth defects. Drugs that treat cancers driven by ''BRAF'' mutations have been developed. Two of these drugs, vemurafenib Vemurafenib (INN, marketed as Zelboraf) is an inhibitor of the B-Raf enzyme developed by Plexxikon (now part of Daiichi-Sankyo) and Genentech for the treatment of late-stage melanoma.; The name "vemurafenib" comes from V600E mutated BRAF in ... and dabrafenib are approved by FDA for treatment of late-stage melanoma. Vemurafenib was the first approved drug to come out of fragment-based drug discovery. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAF1
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 that in humans is encoded by the ''RAF1'' gene. 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. C-Raf is a member of the Raf kinase family of serine/threonine-specific protein kinases, from the TKL (Tyrosine-kinase-like) group of kinases. Discovery The first Raf gene, v-Raf was found in 1983. It was isolated from the murine retrovirus bearing the number 3611. It was soon demonstrated to be capable to transform rodent fibroblasts to cancerous cell lines, so this gene was given the name Virus-induced Rapidly Accelerated Fibrosarcoma (V-RAF). A year later, another transforming gene was found in the avian retrovirus MH2, named v-Mil - that turned out to be highly similar to v-Raf. Researchers were able to demonstrate that these genes encode enzymes th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TAO2
''Tao'' or ''Dao'' is the natural order of the universe, whose character one's intuition must discern to realize the potential for individual wisdom, as conceived in the context of East Asian philosophy, East Asian religions, or any other philosophy or religion that aligns to this principle. This intuitive knowing of life cannot be grasped as a concept. Rather, it is known through actual living experience of one's everyday being. Its name, ''Tao'' or ''Dao'' , came from Chinese, where it signifies the way, path, route, road, or sometimes more loosely doctrine, principle, or holistic belief. Laozi in the ''Tao Te Ching'' explains that the ''Tao'' is not a name for a thing, but the underlying natural order of the Universe whose ultimate essence is difficult to circumscribe because it is non-conceptual yet evident in one's being of aliveness. The Tao is "eternally nameless" (''Tao Te Ching''-32. Laozi) and to be distinguished from the countless named things that are considered to ...

MAP3K15
Mitogen-activated protein kinase kinase kinase 15 is a protein that in humans is encoded by the MAP3K15 gene. Function The protein encoded by this gene is a member of the mitogen-activated protein kinase (MAPK) family. These family members function in a protein kinase signal transduction cascade, where an activated MAPK kinase kinase (MAP3K) phosphorylates and activates a specific MAPK kinase (MAP2K), which then activates a specific MAPK. This MAP3K protein plays an essential role in apoptotic cell death Apoptosis (from grc, ἀπόπτωσις, apóptōsis, 'falling off') is a form of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes (morphology) and death. These changes includ ... triggered by cellular stresses.

MAP3K14
Mitogen-activated protein kinase kinase kinase 14 also known as NF-kappa-B-inducing kinase (NIK) is an enzyme that in humans is encoded by the ''MAP3K14'' gene. Function This gene encodes mitogen-activated protein kinase kinase kinase 14, NIK, which is a serine/threonine protein-kinase. This kinase binds to TRAF2 and stimulates NF-κB activity. It is a critical kinase of the alternative NF-κB activation pathway. It shares sequence similarity with several other MAPKK kinases. It participates in an NF-κB-inducing signalling cascade common to receptors of the tumour-necrosis/nerve-growth factor (TNF/ NGF) family and to the interleukin-1 type-I receptor.
