B- and T-lymphocyte attenuator (BTLA; CD272) is a 35 kDa type I transmembrane glycoprotein in the CD28 family of T cell costimulatory molecules. BTLA is a inhibitory receptor on lymphocytes that negatively regulates antigen receptor signaling via PTPN6/SHP-1 and PTPN11/SHP-2. BTLA may interact in cis (on the same cell) or in trans (on other cells) with TNFRSF14. BTLA Protein, Human, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 16.7 kDa and the accession number is Q7Z6A9-1.

BTLA Protein, Human, Recombinant (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with His and Avi tag. The predicted molecular weight is 17 kDa.

BTLA Protein, Human, Recombinant (isoform1,hFc) is expressed in HEK293 mammalian cells with hFc tag. The predicted molecular weight is 40.47 kDa and the accession number is NP_861445.4.

BTLA Protein, Human, Recombinant (isoform 1,mFc) is expressed in HEK293 mammalian cells with mFc tag. The predicted molecular weight is 40.56 kDa and the accession number is NP_861445.4.

B- and T-Lymphocyte Attenuator (BTLA) is a single-pass type I membrane protein containing 1 Ig-like V-type (immunoglobulin-like) domain. BTLA expression is induced during activation of T cells, and BTLA remains expressed on Th1 cells but not Th2 cells. Like PD1 and CTLA4, BTLA interacts with a B7 homolog, B7H4. However, unlike PD-1 and CTLA-4, BTLA displays T-Cell inhibition via interaction with tumor necrosis family receptors (TNF-R), not just the B7 family of cell surface receptors. BTLA is a lymphocyte inhibitory receptor that inhibits lymphocytes during immune response. BTLA also is a ligand for tumor necrosis factor (receptor) superfamily, member 14 (TNFRSF14), also known as herpes virus entry mediator (HVEM). BTLA-HVEM complexes negatively regulate T-cell immune responses.
