背景介绍 NEK11 is a member of the NEK family and the protein localizes to the nucleoli where it may function with NEK2A in the S-phase checkpoint. NEK2 phosphorylates NEK11 in its C-terminal autoinhibitory domain and elevates NEK11 kinase activity by dissociating the autoinhibitory domain from the N-terminal catalytic domain (1). NEK11 protein appears to play a role in DNA replication and response to genotoxic stress. NEK11 activity is activated in HeLa cells treated with various DNA-damaging agents and replication inhibitors. Activation of NEK11 by genotoxic agents is suppressed by inhibitor of ATR/ATM-mediated signalling indicating that NEK11 has a role in S-phase checkpoint downstream of ATR/ATM signalling (2). 产品介绍 Recombinant human NEK11, full length, with N-terminal GST-tag, expressed by Sf9 insect cells via a baculovirus expression system.
询价背景介绍 NDR or Nuclear Dbf2-related protein is a serine/threonine kinase in the subgroup of the AGC kinase family that is regulated by Mob proteins (1). Fas and TNFα receptor stimulation activates human NDR by promoting phosphorylation at the hydrophobic motif. NDR acts as a novel pro-apoptotic kinase, and is a key member of the RASSF1A/MST1 signaling cascade (2). NDR is crucial for the fidelity of mitotic chromosome alignment in mammalian cells. NDR is incorporated into the HIV-1 particles and is cleaved by the HIV-1 protease. NDR-driven centrosome duplication requires Cdk2 activity, and Cdk2-induced centrosome amplification is affected upon reduction of NDR activity. 产品介绍 Recombinant human NDR, full length, with N-terminal GST-tag, expressed by Sf9 insect cells via a baculovirus expression system.
询价背景介绍 MYO3β is a member of the Class III myosins that are actin-dependent motor proteins containing an amino-terminal kinase domain. MYO3β contains an N-terminal kinase domain, followed by motor, neck, and tail domains. The MYO3β gene generates a variety of splice variants that contain 1 or 2 calmodulin-binding (IQ) motifs in the neck domain and 1 of 3 domains in the tail domain. Northern blot analysis shows expression of a 7-kb MYO3β transcript in the human retina but not in a RPE cell line (1). The MYO3β gene transcript is also detected in the kidney, intestine and testis. The MYO3β gene maps to chromosome 2q31.1-q31.2 by genomic sequence alignment. 产品介绍 Recombinant Human MYO3β (a.a. 1-326), with N-terminal GST-tag, expressed by Sf9 insect cells via a baculovirus expression system.
询价背景介绍 MYLK3 (or myosin light chain kinase 3) plays a key role in rate of cross-bridge recruitment in cardiac myocytes. MYLK3 is upregulated in failing human myocardia and expression of MYLK3 correlates with the pulmonary arterial pressure of patients with heart failure (1). Knockdown of MYLK3 with small interfering RNAs in cultured rat cardiomyocytes decreases Myl2 phosphorylation and impairs epinephrine-induced activation of sarcomere reassembly (2). Recombinant murine MYLK3 shows specificity for Myl2 (Mlc2v) and the phosphorylation is calcium- and calmodulin-dependent. 产品介绍 Recombinant human MYLK3, full length, with N-terminal GST-tag, expressed by Sf9 insect cells via a baculovirus expression system.
询价背景介绍 MYLK2 is a member of the myosin light chain kinase family and is a calcium/calmodulin dependent enzyme that is exclusively expressed in adult skeletal muscle (1). MYLK2 has been proposed to participate in signaling pathways (calcium signaling pathway, focal adhesion, regulation of actin cytoskeleton) and cellular processes (neuromuscular synaptic transmission, protein/amino acid phosphorylation). MYLK2 is involved in multiple molecular functions as a result of various subdomains that participate in ATP binding, calmodulin binding, nucleotide binding, protein serine/threonine kinase activity and transferase activity) (2). 产品介绍 Recombinant human MYLK2, full length, with N-terminal His-tag, expressed by Sf9 insect cells via a baculovirus expression system.
询价背景介绍 MST4 belongs to a family of proteins that share similarity with a budding yeast serine/threonine kinase, sterile-20 (Ste20), and have a role in mitogen-activated protein kinase signaling during cytoskeletal rearrangement, morphogenesis, apoptosis, and other diverse cellular events (1). Expression of MST4 has been shown to correlate with tumorigenicity and inversely with androgen receptor status in a number of human prostate cancer cell lines. Overexpression of MST4 induced anchorage-independent growth and increased in vitro proliferation of these prostate cancer cell lines (2). 产品介绍 Recombinant human MST4, also known as MASK (GenBank Accession No. NM_016542), full length, with N-terminal GST tag, MW=72 kDa, expressed in Sf9 insect cells via a baculovirus expression system.
询价背景介绍 MST3 or Mammalian Sterile 20-like kinase 3 is a member of the germinal center kinase-III family. MST3 contains a conserved kinase domain at its NH(2)-terminus and a regulatory domain at its COOH-terminus. Caspase-mediated cleavage of the regulatory domain of MST3 activates its intrinsic kinase activity and leads to nuclear translocation. Expression of COOH-terminal truncated MST3 in cells results in DNA fragmentation and induction of apoptosis (1). MST3 can inhibit cell migration in a fashion dependent on autophosphorylation and can regulate paxillin phosphorylation through tyrosine phosphatase PTP-PEST (2). 产品介绍 Recombinant human MST3 (a.a. 1-311), with N-terminal GST-tag, expressed by Sf9 insect cells via a baculovirus expression system.
询价背景介绍 MSSK1, also known as SRPK3, is a muscle-specific protein kinase belonging to the serine arginine protein kinase family which phosphorylates serine/arginine repeat-containing proteins. Heart and skeletal muscle show high expression of the MSSK1/SRPK3 gene product. SRPK3-null mice display a new entity of type 2 fiber-specific myopathy with a marked increase in centrally placed nuclei. Transgenic mice overexpressing SRPK3 in skeletal muscle show severe myofiber degeneration and early lethality (1). 产品介绍 Recombinant human MSSK1 (SRPK3), full length, with N-terminal GST-tag, expressed in Sf9 insect cells via a baculovirus expression system.
询价背景介绍 MSK1 or mitogen- and stress-activated protein kinase-1 contains 2 protein kinase domains and shares 43% protein sequence identity with the MAPKAPK1 isoforms. Northern blot analysis shows that MSK1 is expressed in all tissues with the highest level of expression in brain, muscle, and placenta. Immunoelectron microscopy localized MSK1 to the nucleus. MSK1 is activated in vitro and in vivo by either ERK or SAPK2 proteins. MSK1 rather than MAPKAP-K1 or MAPKAP-K2/K3, mediates activation of the cAMP response element-binding protein and activating transcription factor-1 by either growth factors or stress signals. By radiation hybrid analysis, the RPS6KA5 gene has been mapped to chromosome 14q31-q32. 产品介绍 Recombinant human MSK1, full length, with N-terminal GST-tag, expressed by Sf9 insect cells via a baculovirus expression system.
