Clone Host Grade Applications
Monoclonal Rat Affinity Purified E B
B and T Lymphocyte Attenuator (BTLA) also known as CD272, is a 70kD type I transmembrane glycoprotein of the CD28 family of T cell costimulatory molecules. BTLA functions as a coinhibitor on activated T cells and on B cells and dendritic cells. The extracellular domain (ECD) of this Ig superfamily protein contains one V-type Ig-like domain, which interacts with the Herpes virus entry mediator (HVEM/TNFSF14). The amino acid sequence of the ECD of human BTLA shares only 34% identity to that of mouse BTLA. One human BTLA variant lacking the transmembrane sequence has been reported.
