Recombinant Human ULBP1 Protein (Gly26-Pro215), C-Fc-tagged
Product Description
Cat
IMP-9682
Official Symbol
ULBP1
Product Overview
Recombinant human ULBP-1 protein (Gly26-Pro215) with a human IgG1 (Pro100-Lys330) Fc tag at C-terminus was expressed in Spodoptera frugiperda, Sf 21 (stably transfected) cells.
Description
The protein encoded by this gene is a ligand of natural killer group 2, member D (NKG2D), an immune system-activating receptor on NK cells and T-cells. Binding of the encoded ligand to NKG2D leads to activation of several signal transduction pathways, including those of JAK2, STAT5, ERK and PI3K kinase/Akt. Also, in cytomegalovirus-infected cells, this ligand binds the UL16 glycoprotein and is prevented from activating the immune system. Three transcript variants encoding different isoforms have been found for this gene.
