function:Receptor for BTLA. Receptor for TNFSF14/LIGHT and homotrimeric TNFSF1/lymphotoxin-alpha. Involved in lymphocyte activation. Plays an important role in HSV pathogenesis because it enhanced the entry of several wild-type HSV strains of both serotypes into CHO cells, and mediated HSV entry into activated human T-cells.,PTM:N-glycosylated.,similarity:Contains 3 TNFR-Cys repeats.,subunit:Interacts with TRAF2, TRAF3 and TRAF5.,tissue specificity:Widely expressed, with the highest expression in lung, spleen and thymus.,
Cell membrane ; Single-pass type I membrane protein .
Widely expressed, with the highest expression in lung, spleen and thymus. Expressed in a subpopulation of B cells and monocytes (PubMed:18193050). Expressed in naive T cells (PubMed:19915044).
