Background

Mouse B7-H2, also called B7RP-1, B7h, LICOS, and GL50, is a member of the growing B7 family of immune costimulatory proteins. Other family members include B7-1, B7-2, B7-H1 (PD-L1), PD-L2, and B7-H3. B7 proteins are members of the immunoglobulin (Ig) superfamily. The extracellular domains contain 2 Ig-like domains and all members have short cytoplasmic domains. Among the family members, they share about 20‑25% amino acid identity. Mouse and human B7-H2 share approximately 49% amino acid identity. B7-H2 has been identified as the ligand for ICOS, a member of the CD28 family of costimulatory receptors. Mouse B7-H2 is a 322 amino acid (aa) protein with a putative 46 aa signal peptide, a 233 aa extracellular domain, a 19 aa transmembrane region, and a 24 aa cytoplasmic domain. Mouse B7-H2 is expressed constitutively on resting B cells and at low levels on monocytes. The B7-H2/ICOS interaction appears to play roles in T cell dependent B cell activation and T_h differentiation.
