Descriptionc-Kit (V654A) Protein, active, 10 µg
OverviewN-terminal GST tagged, recombinant human cKit, amino acids 544 - end containing the V654A mutation. Co-ordinates encompass the cytoplasmic domain (544-976) according in Swiss Prot P10721. V654A is an acquired resistance mutation which has been found in patients with gastrointestinal stromal tumours (GISTs) undergoing treatment with Imatinib. The V654A mutation is strongly correlated with imatinib resistance and rapid progession of GISTs. (Chen LL et al., Cancer Research, (2004); 64:5913-5919).

Applications
ApplicationV654A is an acquired resistance mutation found in patients with gastrointestinal stromal tumours (GISTs) undergoing treatment with Imatinib. The V654A mutation is strongly correlated with imatinib resistance & rapid progession of GISTs.
Key Applications
  • Kinase Assay
Biological Information
Sourcerecombinant protein expressed in Sf21 cells
Specific Activity169 U/mg, where one unit of cKit (V654A) activity is defined as 1nmol phosphate incorporated into 250 μM GGMEDIYFEFMGGKKK per minute at 30 °C with a final ATP concentration of 100 μM.
Entrez Gene Number
Entrez Gene SummaryThis gene encodes the human homolog of the proto-oncogene c-kit. C-kit was first identified as the cellular homolog of the feline sarcoma viral oncogene v-kit. This protein is a type 3 transmembrane receptor for MGF (mast cell growth factor, also known as stem cell factor). Mutations in this gene are associated with gastrointestinal stromal tumors, mast cell disease, acute myelogenous lukemia, and piebaldism. Multiple transcript variants encoding different isoforms have been found for this gene.

Purification MethodPurified using glutathione-agarose. Purity 99% by SDS-PAGE and Coomassie blue staining.
Target Sub-FamilyTK
UniProt Number
UniProt SummaryFUNCTION: SwissProt: P10721 # This is the receptor for stem cell factor (mast cell growth factor). It has a tyrosine-protein kinase activity. Binding of the ligands leads to the autophosphorylation of KIT and its association with substrates such as phosphatidylinositol 3-kinase (Pi3K).
SIZE: 976 amino acids; 109865 Da
SUBUNIT: Interacts with APS. Interacts with the tenth PDZ domain of MPDZ.
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
DISEASE: SwissProt: P10721 # Defects in KIT are a cause of piebaldism [MIM:172800]. Piebaldism is an autosomal dominant genetic developmental abnormality of pigmentation characterized by congenital patches of white skin and hair that lack melanocytes. & Defects in KIT are a cause of gastrointestinal stromal tumor (GIST) [MIM:606764]. & Defects in KIT have been associated with testicular tumors [MIM:273300]. It includes germ cell tumor (GCT) or testicular germ cell tumor (TGCT).
SIMILARITY: SwissProt: P10721 ## Belongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily. & Contains 5 Ig-like C2-type (immunoglobulin-like) domains. & Contains 1 protein kinase domain.
Molecular Weight76.7kDa.
