TACI, transmembrane activator and CAML-interactor, is a member of the TNF receptor superfamily. TACI is a type III membrane protein with an extracellular
N‑terminus in the absence of a cleaved signal sequence. The extracellular region of TACI contains two cysteine rich domains. Within the TNFRSF, it shares the highest homology with BCMA. TACI and BCMA have both been shown to bind APRIL and BAFF, members of the TNF ligand superfamily. TACI is expressed on the cell surface of B cells and activated, but not resting, T cells. Analogous to BCMA, data suggests that TACI may play an important role in B cell development, function and regulation. Human TACI is a 293 amino acid (aa) protein consisting of a 166 aa extracellular domain, a 20 aa transmembrane domain, and a 107 aa intracellular domain. Human and mouse TACI share 54% amino acid identity.
