Biotinylated Human KIR3DL3 / CD158z Protein, Fc, Avitag™

The inhibitory KIR surface receptors possessing three extracellular immunoglobin (Ig) domains (3D) and only one inhibitory motif within the long cytoplasmic domain (L) due to a premature stop codon. Moreover, exon 6 of KIR3DL3 encoding the stem part of the receptor is also absent, which differs from other inhibitory KIRs. Understanding the function of KIR3DL3 is further complicated by the unknown identity of the specific ligand, but its importance is highlighted by its presence in all human KIR haplotypes with 120 distinct polymorphic alleles of the coding sequence [

Background

Specifications

This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™) . The protein has a calculated MW of 60.4 kDa. The protein migrates as 66-80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
