Human B7 homolog 3 (B7-H3) is a member of the B7 family of immune proteins that provide signals for the regulation of immune responses. Its precursor contains a 26 aa signal sequence, a 435 aa extracellular region, a 31 aa transmembrane domain, and a 42 aa cytoplasmic tail. The four Ig-like domains alternate between Vtype and Ctype, and apparently are the consequence of a VC type tandem duplication. Human B7-H3b binding to an undefined receptor has shown to be inhibitory to NK cell illing and cytokine release.
