Short name: NK_rcpt_2B4_Ig_dom

Domain relationships

Description

2B4 is a transmembrane receptor which is expressed primarily on natural killer (NK) cells. It plays a role in activating NK-mediated cytotoxicity through its interaction with CD48 on target cells in a subset of CD8 T cells [PMID: 15850375]. The structure of 2B4 consists of an immunoglobulin variable domain fold and contains two beta-sheets. One of the beta-sheets, the six-stranded sheet, contains structural features that may have a role in ligand recognition and receptor function [PMID: 15850375].

This entry represents the 2B4 immunoglobulin domain.
