分子别名(Synonym)

KITLG,FPH2,KL-1,Kitl,MGF,SCF,SF,SHEP7,KL

表达区间及表达系统(Source)

Mouse SCF, His Tag (SCF-M5228) is expressed from human 293 cells (HEK293). It contains AA Lys 26 - Ala 189 (Accession # NP_038626).

Predicted N-terminus: Lys 26

蛋白结构(Molecular Characterization)

Online(Lys 26 - Ala 189) NP_038626

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 19.5 kDa. The protein migrates as 19-30 kDa under reducing (R) condition (SDS-PAGE) due to different glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Protocol

背景(Background)

Kit ligand (KITLG) is also known as stem cell factor (SCF), mast cell growth factor (MGF), steel factor (SF), which belongs to the SCF family, and is a widely expressed 28 - 40 kDa type I transmembrane glycoprotein. KITLG is the ligand for the receptor-type protein-tyrosine kinase KIT. SCF / MGF 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. KITLG / SCF binding can activate several signaling pathways. KITLG / SF Promotes phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, and subsequent activation of the kinase AKT1. KITLG / SCF and KIT also transmit signals via GRB2 and activation of RAS, RAF1 and the MAP kinases MAPK1/ERK2 and/or MAPK3/ERK1. KITLG / SCF and KIT promote activation of STAT family members STAT1, STAT3 and STAT5. KITLG / SCF and KIT promote activation of PLCG1, leading to the production of the cellular signaling molecules diacylglycerol and inositol 1, 4, 5 - trisphosphate. KITLG / SCF acts synergistically with other cytokines, probably interleukins.
