KIR3DS1/CD158e2 Protein, Human (CHO, His)

Customer Review

Based on 1 Customer Validation

KIR3DS1/CD158e2, located on NK cells, serves as a receptor for MHC class I molecules. Its crucial role includes triggering NK cell degranulation and inducing the production of anti-viral cytokines upon interaction with the peptide-free HLA-F open conformer. This direct engagement highlights KIR3DS1/CD158e2 as a key modulator of NK cell responses, particularly in anti-viral immune reactions. KIR3DS1/CD158e2 Protein, Human (CHO, His) is the recombinant human-derived KIR3DS1/CD158e2 protein, expressed by CHO , with tag free.

Description

KIR3DS1/CD158e2, located on NK cells, serves as a receptor for MHC class I molecules. Its crucial role includes triggering NK cell degranulation and inducing the production of anti-viral cytokines upon interaction with the peptide-free HLA-F open conformer. This direct engagement highlights KIR3DS1/CD158e2 as a key modulator of NK cell responses, particularly in anti-viral immune reactions. KIR3DS1/CD158e2 Protein, Human (CHO, His) is the recombinant human-derived KIR3DS1/CD158e2 protein, expressed by CHO , with tag free.

Background

KIR3DS1/CD158e2, situated on natural killer (NK) cells, functions as a receptor for MHC class I molecules. Its pivotal role involves triggering NK cell degranulation and promoting the production of anti-viral cytokines upon interaction with the peptide-free HLA-F open conformer. The direct interaction with HLA-F open conformer underscores the specificity of this receptor-ligand engagement, highlighting KIR3DS1/CD158e2 as a key player in modulating NK cell responses, particularly in the context of anti-viral immune reactions.
