背景介绍 GRK5 is a member of the guanine nucleotide-binding protein (G protein)-coupled receptor kinase subfamily of the Ser/Thr protein kinase family (1). It phosphorylates the activated forms of G protein-coupled receptors thus initiating their deactivation. GRK5 plays a role in regulating the motility of polymorphonuclear leukocytes (PMNs). Desensitization of G protein-coupled receptors regulates the number of polymorphonuclear leukocytes (PMNs), as well as their motility and ability to stop upon contact with pathogens or target cells, and this desensitization is mediated by GRK5 (2). 产品介绍 Human GRK5, also known as GPRK5 (GenBank Accession No. NM_005308), full length, with N-terminal GST tag, MW ~95 kDa, expressed in Sf9 insect cells via a baculovirus expression system.
询价背景介绍 GRK2 or ADRBK1 is a ubiquitous cytosolic enzyme that specifically phosphorylates the activated form of the beta-adrenergic and related G protein-coupled receptors. GRK2 phosphorylates the beta-2-adrenergic receptor and appears to mediate agonist-specific desensitization. Abnormal coupling of beta-adrenergic receptor to G protein is involved in the pathogenesis of the failing heart (1). RAF kinase inhibitor protein RKIP is a physiologic inhibitor of GRK2 (2). After stimulation of G protein-coupled receptors, RKIP dissociates from its known target, RAF1 to associate with GRK2 and block its activity. 产品介绍 Recombinant human GRK2, full length, with N-terminal GST-tag, expressed in Sf9 insect cells via a baculovirus expression system.
询价背景介绍 EIF2AK3 phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2 (EIF2) leading to its inactivation and a rapid reduction of translational initiation and repression of global protein synthesis. EIF2AK3 is a type I membrane protein located in the endoplasmic reticulum (ER), where it is induced by ER stress caused by malfolded proteins (1). EIF2AK3 plays a major role in the ability of cells to adapt to ER stress and is also involved in an integrated adaptive response to hypoxic stress in HeLa cells (2). EIF2AK3 functions in iron homeostasis and may play a role in hemolytic and inflammatory anemia. 产品介绍 Recombinant human EIF2AK3 (a.a. 563-1115), with N-terminal GST-tag, expressed in E. coli cells
询价背景介绍 EIF2AK2 (also known as double-stranded RNA-activated protein kinase) is a protein kinase that has been shown to be involved in HIV/gp120-associated neurodegeneration (1). EIF2AK2 acts as a critical mediator of gp120 neurotoxicity and is a substrate for a family of protein kinases that respond to various forms of environmental stress. Activation of EIF2AK2 leads to its autophosphorylation and then phosphorylation of its natural substrate, the alpha subunit of eukaryotic protein synthesis initiation factor-2. EIF2AK2 plays a critical role in mRNA translation, cell proliferation and apoptosis. A novel cross-talk between the EIF2AKs and p53 has been shown that has implications in cell proliferation and tumorigenesis (2). 产品介绍 Recombinant human EIF2AK2 (a.a. 252-end), with N-terminal GST-tag, expressed in Sf9 insect cells via a baculovirus expression system.
询价背景介绍 EEF2K is a highly conserved calmodulin-dependent protein kinase that links activation of cell surface receptors to cell division. EEF2K is involved in the regulation of protein synthesis. It phosphorylates eukaryotic elongation factor 2 (EEF2), an abundant cytoplasmic protein that catalyzes the movement of the ribosome along mRNA during translation in eukaryotic cells, and inhibits the EEF2 function (1). EEF2K is highly expressed in heart and skeletal muscle, suggesting that EEF2 phosphorylation may be particularly important in muscle. EEF2K is highly expressed in patients with systemic lupus erythematosus (2) as well as in many cancers. 产品介绍 Recombinant human eukaryotic elongation factor 2 (EEF2K), full length, with N-terminal GST-tag, expressed by Sf9 insect cells via a baculovirus expression system.
询价背景介绍 ERK1 is a protein serine/threonine kinase that is a member of the extracellular signal-regulated kinases (ERKs) which are activated in response to numerous growth factors and cytokines (1). Activation of ERK1 requires both tyrosine and threonine phosphorylation that is mediated by MEK. ERK1 is ubiquitously distributed in tissues with the highest expression in heart, brain and spinal cord. Activated ERK1 translocates into the nucleus where it phosphorylates various transcription factors (e.g., Elk-1, c-Myc, c-Jun, c-Fos, and C/EBP beta). 产品介绍 Recombinant full-length, tag-free human ERK1 was expressed in Sf9 cells and activated by active MEK1 in vitro. The gene accession number is NM_002746.
询价背景介绍 DMPK (or Myotonic Dystrophy Protein Kinase) is a serine-threonine kinase that is closely related to other kinases that interact with members of the Rho family of small GTPases. DMPK protein has a leucine-rich domain at the N-terminus, a serine/threonine kinase domain in the middle, and a hydrophobic region at the C-terminus. The N-terminus of DMPK plays an important role in DMPK kinase activity, and the C-terminus of DMPK determines the intracellular localization of the protein (1). Myotonic dystrophy type 1 is an autosomal dominant disease caused by a trinucleotide repeat-expansion, cytosine-thymine-guanine (CTG)n, in the 3' untranslated region of DMPK (2). 产品介绍 Recombinant human DMPK, full length, with N-terminal GST-tag, expressed by Sf9 insect cells via a baculovirus expression system.
询价背景介绍 DAPK3 or Death-associated protein kinase 3 (also known as ZIP) plays a role in apoptosis (1). DAPK3 is a nuclear serine/threonine-specific kinase that phosphorylates core histones H3 and H4, and myosine light chain in vitro. DAPK3 interacts with transcription and splicing factors as well as with pro-apoptotic protein Par-4 suggesting that it participates in multiple cellular processes. DAPK3 contains a leucine zipper structure at its C terminus and this region is responsible for binding to ATF4. The leucine zipper domain is necessary for the homodimerization of DAPK3 as well as for the activation of the kinase (2). 产品介绍 Recombinant human DAPK3, full length, with N-terminal GST-tag, expressed in Sf9 insect cells via a baculovirus expression system.
