| Background | B- and T-lymphocyte attenuator (CD272/BTLA) is a ~32 kDa protein. Inhibitory receptor on lymphocytes that negatively regulates antigen receptor signaling via PTPN6/SHP-1 and PTPN11/SHP-2. May interact in cis (on the same cell) or in trans (on other cells) with TNFRSF14. In cis interactions, appears to play an immune regulatory role inhibiting in trans interactions in naive T cells to maintain a resting state. In trans interactions, can predominate during adaptive immune response to provide survival signals to effector T cells. 1. Watanabe, N. et al. (2003) Nature immunology 4, 670-9. PMID: 12796776 2.
