Description

B7-H3(4Ig) or B7-H3b has two additional Ig-like domains (one V- type and one C- type) and shows a ubiquituous expression pattern. B7-H3(4Ig) is expressed on dendritic cells as well as activated T, B and NK cells. Human (4Ig) binding to an undefined receptor has shown to be inhibitory to NK cell illing and cytokine release. It also seems to be required for late stage osteoblast differentiation.
