Background: BTN2A1

Butyrophilin 2A1 (BTN2A1) is a type I transmembrane glycoprotein of the butyrophilin family within the Ig-superfamily. There are over 13 Butyrophilin and the closely related butyrophilin-like (BTNL) molecules and they have been identified as immune checkpoint receptors involved in modulating T cell function (1,2). Mature human BTN2A1 consists of an extracellular domain (ECD) with two immunoglobulin-like domains (one IgV and one IgC), a transmembrane segment, and a cytoplasmic region with a B30.2 domain (3). Alternative splicing generates additional isoforms of BTN2A1 that lack the first Ig-like domain or the transmembrane segment as well as isoforms with substitutions and deletions in the cytoplasmic region. BTN2A1 is widely expressed including on colonic epithelial cells, on immune cells, and in milk fat globules (4, 5). BTN2A1 binds to the C-type lectin DC-SIGN on monocyte-derived dendritic cells, and this interaction can be blocked by soluble gp130 from HIV (4). A polymorphism of BTN2A1 has been associated with metabolic syndromes, type II diabetes mellitus, chronic kidney disease, and hypertension (6, 7).
