B7-H3 or CD276 is a 316aa long type I transmembrane protein. B7-H3 shares 20-27% amino acid identity with other B7 family ligands. Glycosylated B7-H3 protein has a molecular weight of approximately 100 kDa. A B7-H3 soluble isoform has been detected in plasma and B7-H3 is also expressed on exosomes. B7-H3 is ubiquitously expressed by cells in the non-hematopoietic compartment, such as fibroblasts and epithelial cells, it can be induced on T cells and NK cells.
