Butyrophilin Subfamily 3 Member A1 (BTN3A1 CD277) is a type I transmembrane glycoprotein member of the Ig superfamily. It is expressed on a wide variety of immune cells. Similar to BTN3A2 and BTN3A3, BTN3A1 is composed of an extracellular N-terminal IgV and a membraneproximal IgC domain followed by a transmembrane domain and a cytoplasmic tail. These Ig domains are also found in B7 family costimulatory molecules, suggesting structural and functional similarities between the two protein families. BTN3A1 acts as a critical protein for the activation of Vγ9Vδ2 T cells following detection of distressed cells. The anti-tumor responses of Vγ9Vδ2 T cells may be enhanced with agonistic anti-BTNA3 antibodies.

BTN3A1 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 25.6 kDa and the accession number is O00481-2.

BTN3A1 Protein, Human, Recombinant is expressed in HEK293 mammalian cells. The predicted molecular weight is 24.16 kDa and the accession number is NP_919423.1.

The three butyrophilin BTN3A molecules, BTN3A1, BTN3A2, and BTN3A3, are members of the B7 butyrophilin-like group of Ig superfamily receptors, which modulate the function of T cells. BTN3A1 controls activation of human Vγ9 Vδ2 T cells by direct or indirect presentation of self and nonself phosphoantigens (pAg). BTN3A1 Protein, Cynomolgus, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 26.5 kDa and the accession number is A0A330KWZ1.
