Cloning of TRAP, a ligand for CD40 on human T cells
1 Dec 1992
Abstract excerpt
A cDNA clone, designated TRAP (TNF-related activation protein) was isolated from a collection of T cell activation genes. The polypeptide encoded by a mRNA of approx. 2.3 kb is 261 amino acids long with a calculated M(r) of 29.3 kDa. The structural features predict a type II transmembrane protein, but are also compatible with a secreted form. TRAP is highly similar to an identified murine CD40 ligand both at the...
