Function

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.

Biological Context

Subcellular Location: Cell membrane (Single-pass type I membrane protein)

Product Specifications

Recombinant Human B- and T-lymphocyte attenuator (BTLA), partial (Active) is a recombinant protein from Homo sapiens (Human), expressed in Mammalian cell, covering amino acids 31-157aa, with C-terminal 10xHis-tagged tag, molecular weight 16.1kDa, purity Greater than 95% as determined by SDS-PAGE..

Inhibitory receptor on lymphocytes that negatively regulates antigen receptor signaling via PTPN6/SHP-1 and PTPN11/SHP-2 (PubMed:12796776, PubMed:14652006, PubMed:15568026, PubMed:18193050). May interact in cis (on the same cell) or in trans (on other cells) with TNFRSF14 (PubMed:19915044). 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 (PubMed:19915044)
