B7 homolog 3 (B7-H3) is a member of the B7 family of immune proteins that provide signals for regulating immune responses. Other family members include B7-1, B7-2, B7-H2, PD-L1 (B7-H1), and PD-L2. B7 proteins are immunoglobulin (Ig) superfamily members with extracellular Ig-V-like and Ig-C-like domains and short cytoplasmic domains. Among the family members, they share about 20-40% aa sequence identity.
