This domain is found in human Butyrophilin subfamily 3 member A2 (BTN3A2), a protein that plays a role in T-cell responses in the adaptive immune response. BTN3A2 shows two extracellular domains: an N-terminal Ig-V like domain (Pfam:PF07686) and a C-terminal Ig-C type domain that is located in the centre of the protein sequence [6].	Domain
