DNAM-1 Protein, Human (Biotinylated, HEK293, His-Avi)

Customer Review

Based on 1 Customer Validation

DNAM-1 protein is a key player in cell-cell adhesion and lymphocyte signaling, mediating cytotoxicity and lymphokine secretion of CTL and NK cells. As a receptor for NECTIN2, DNAM-1 stimulates T cell proliferation and cytokine production (IL2, IL5, IL10, IL13, and IFNG) upon ligand binding. DNAM-1 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived DNAM-1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Biological Activity

Description

DNAM-1 protein is a key player in cell-cell adhesion and lymphocyte signaling, mediating cytotoxicity and lymphokine secretion of CTL and NK cells. As a receptor for NECTIN2, DNAM-1 stimulates T cell proliferation and cytokine production (IL2, IL5, IL10, IL13, and IFNG) upon ligand binding. DNAM-1 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived DNAM-1 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

Background

The DNAM-1 protein is intricately involved in intercellular adhesion, lymphocyte signaling, cytotoxicity, and lymphokine secretion mediated by cytotoxic T-lymphocytes (CTL) and natural killer (NK) cells. Serving as a cell surface receptor for NECTIN2, DNAM-1, upon ligand binding, stimulates T-cell proliferation and the production of cytokines such as IL2, IL5, IL10, IL13, and IFNG. Furthermore, DNAM-1 competes with PVRIG for NECTIN2-binding, underscoring its regulatory role in cellular interactions and signaling pathways. This protein also interacts with PVR and NECTIN2, contributing to its multifaceted functions in immune responses and cellular communication.

Verified Bioactivity

Measured by its binding ability in SPR assay. Human CD155 hFc immobilized on CM5 Chip can bind Biotinylated Human DNAM-1 His-Avi with an affinity constant of 0.503 μM.
