Background: BTNL4

Butyrophilin-like 4, also known as BTLN4, BTN3A3 (human) and BTN3A2 (rat) is an approximately 65 kDa member of the butyrophilin family that may play a role in immune regulation (1-3). The mouse BTNL4 is a 586 aa type 1 transmembrane protein, consisting of a 28 aa signal peptide, followed by a 109 aa immunoglobulin (Ig) V domain, a 71 aa IgC domain, a 20 aa transmembrane domain, and a 170 aa cytoplasmic B30.2/SPRY domain (4). Within the extracellular domain including aa 29‑250, mouse BTNL4 shares 45% and 82% sequence identity with human BTN3A3 and rat BTN3A2, respectively. BTNL4 shows striking sequence similarity to Skint1; is also largely restricted to an epithelial tissue (the small intestine) replete with T cells (4). Our in-house studies showed BTNL4 co-inhibited anti-CD3 induced IL‑2 secretion on CD3+ cells.
