KIR2DS3 Protein, Human (P.pastoris, His)

Customer Review

Based on 1 Customer Validation

KIR2DS3, present on NK cells, selectively recognizes HLA-C alleles. In contrast to inhibitory KIRs, KIR2DS3 lacks inhibitory effects on NK cell activity. Its role is likely in activating or modulating NK cell functions, contributing to the nuanced balance of signals regulating the immune response. KIR2DS3 Protein, Human (P.pastoris, His) is the recombinant human-derived KIR2DS3 protein, expressed by P. pastoris , with N-His labeled tag.

Description

KIR2DS3, present on NK cells, selectively recognizes HLA-C alleles. In contrast to inhibitory KIRs, KIR2DS3 lacks inhibitory effects on NK cell activity. Its role is likely in activating or modulating NK cell functions, contributing to the nuanced balance of signals regulating the immune response. KIR2DS3 Protein, Human (P.pastoris, His) is the recombinant human-derived KIR2DS3 protein, expressed by P. pastoris , with N-His labeled tag.

Background

KIR2DS3, expressed on natural killer (NK) cells, serves as a receptor specifically recognizing HLA-C alleles. In contrast to inhibitory KIRs, KIR2DS3 does not exert inhibitory effects on NK cell activity. Instead, it likely plays a role in activating or modulating NK cell functions, contributing to the intricate balance of signals that regulate the immune response.
