分子別名（Synonym）
CD117,SCFR,c-Kit,KIT
表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）
Biotinylated Cynomolgus CD117 Protein, His,Avitag (CD7-C82E4) is expressed from human 293 cells (HEK293). It contains AA Gln 26 - Thr 521 (Accession # XP_005555329.1).
Predicted N-terminus: Gln 26
蛋白結(jié)構(gòu)（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag?).
The protein has a calculated MW of 59.3 kDa. The protein migrates as 75-100 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
標(biāo)記（Labeling）
Biotinylation of this product is performed using Avitag? technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白標(biāo)記度（Protein Ratio）
Passed as determined by the HABA assay / binding ELISA.
內(nèi)毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
純度（Purity）
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑（Formulation）

背景（Background）
Mast/stem cell growth factor receptor Kit (c-Kit), a member of the protein kinase superfamily, Tyr protein kinase family and CSF-1/PDGF receptor subfamily, is also known as piebald trait protein (PBT), p145 c-kit, tyrosine-protein kinase Kit and CD117,which contains five Ig-like C2-type (immunoglobulin-like) domains and one protein kinase domain. CD117 acts as cell-surface receptor for the cytokine KITLG/SCF and plays an essential role in the regulation of cell survival and proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, migration and function, and in melanogenesis. In response to KITLG/SCF binding, CD117 can activate several signaling pathways. Furthermore, Activated KIT promotes phosphorylation of the protein phosphatases PTPN6/SHP-1 and PTPRU, and of the transcription factors STAT1, STAT3, STAT5A and STAT5B.
