MAPK1
Mitogen-activated protein kinase 1 (MAPK 1), also known as ERK2, is an enzyme that in humans is encoded by the ''MAPK1'' gene. Function The protein encoded by this gene is a member of the MAP kinase family. MAP kinases, also known as extracellular signal-regulated kinases (ERKs), act as an integration point for multiple biochemical signals, and are involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. The activation of this kinase requires its phosphorylation by upstream kinases. Upon activation, this kinase translocates to the nucleus of the stimulated cells, where it phosphorylates nuclear targets. Two alternatively spliced transcript variants encoding the same protein, but differing in the UTRs, have been reported for this gene. MAPK1 contains multiple amino acid sites that are phosphorylated and ubiquitinated. Interactions MAPK1 has been shown to interact with: * ADAM17, * CIITA, * ...

MAP Kinase
A mitogen-activated protein kinase (MAPK or MAP kinase) is a type of serine/threonine-specific protein kinases involved in directing cellular responses to a diverse array of stimuli, such as mitogens, osmotic stress, heat shock and proinflammatory cytokines. They regulate cell functions including proliferation, gene expression, differentiation, mitosis, cell survival, and apoptosis. MAP kinases are found in eukaryotes only, but they are fairly diverse and encountered in all animals, fungi and plants, and even in an array of unicellular eukaryotes. MAPKs belong to the CMGC (CDK/MAPK/GSK3/CLK) kinase group. The closest relatives of MAPKs are the cyclin-dependent kinases (CDKs). Discovery The first mitogen-activated protein kinase to be discovered was ERK1 (MAPK3) in mammals. Since ERK1 and its close relative ERK2 (MAPK1) are both involved in growth factor signaling, the family was termed "mitogen-activated". With the discovery of other members, even from distant organisms (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MAPK14
Mitogen-activated protein kinase 14, also called p38-α, is an enzyme that in humans is encoded by the ''MAPK14'' gene. MAPK14 encodes p38α mitogen-activated protein kinase (MAPK) which is the prototypic member of the p38 MAPK family. p38 MAPKs are also known as stress-activated serine/threonine-specific kinases (SAPKs). In addition to MAPK14 for p38α MAPK, the p38 MAPK family has three additional members, including MAPK11, MAPK12 and MAPK13 which encodes p38β MAPK, p38γ MAPK and p38δ MAPK isoforms, respectively. p38α MAPK was originally identified as a tyrosine phosphorylated protein detected in activated immune cell macrophages with an essential role in inflammatory cytokine induction, such as Tumor Necrotic Factor α (TNFα). However, p38α MAPK mediated kinase activity has been implicated in many tissues beyond immune systems. p38α MAPK is mainly activated through MAPK kinase kinase cascades and exerts its biological function via downstream substrate phosphoryl ...

DUSP1
Dual specificity protein phosphatase 1 is an enzyme that in humans is encoded by the ''DUSP1'' gene. Function The expression of DUSP1 gene is induced in human skin fibroblasts by oxidative/heat stress and growth factors. It specifies a protein with structural features similar to members of the non-receptor-type protein-tyrosine phosphatase family, and which has significant amino-acid sequence similarity to a Tyr/Ser-protein phosphatase encoded by the late gene H1 of vaccinia virus. The bacterially expressed and purified DUSP1 protein has intrinsic phosphatase activity, and specifically inactivates mitogen-activated protein (MAP) kinase in vitro by the concomitant dephosphorylation of both its phosphothreonine and phosphotyrosine residues. Furthermore, it suppresses the activation of MAP kinase by oncogenic ras in extracts of Xenopus oocytes. Thus, DUSP1 may play an important role in the human cellular response to environmental stress as well as in the negative regulation of ...

STAT5A
Signal transducer and activator of transcription 5A is a protein that in humans is encoded by the ''STAT5A'' gene. ''STAT5A'' orthologs have been identified in several placentals for which complete genome data are available. Structure STAT5a shares the same six functional domains as the other members of the STAT family. It contains 20 amino acids unique to its C-terminal domain and is 96% similar to its homolog, STAT5b. The six functional domains and their corresponding amino acid positions are as follows: * N-Terminal domain (aa1-144): stabilized interactions to form tetramers * Coiled-coil domain (aa145-330): interacts with chaperones and facilitates protein-protein interactions for transcriptional regulation * DNA binding domain (aa331-496): permits binding to consensus gamma-interferon activation sequence (GAS) * Linker domain (aa497-592): stabilizes DNA binding * Src Homology 2 domain (aa593-685): mediates receptor-specific recruitment and STAT dimerization via phosphor ...

HDAC4
Histone deacetylase 4, also known as HDAC4, is a protein that in humans is encoded by the ''HDAC4'' gene. Function Histones play a critical role in transcriptional regulation, cell cycle progression, and developmental events. Histone acetylation/deacetylation alters chromosome structure and affects transcription factor access to DNA. The protein encoded by this gene belongs to class II of the histone deacetylase/acuc/apha family. It possesses histone deacetylase activity and represses transcription when tethered to a promoter. This protein does not bind DNA directly but through transcription factors MEF2C and MEF2D. It seems to interact in a multiprotein complex with RbAp48 and HDAC3. Furthermore, HDAC4 is required for TGFbeta1-induced myofibroblastic differentiation. Clinical significance Studies have shown that HDAC4 regulates bone and muscle development. Harvard University researchers also concluded that it promotes healthy vision: Reduced levels of the protein led to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
