May play a role as a mediator of inflammation and angiogenesis. In 10-day embryos B94 is expressed prominently in the myocardium and in the aortic arch. By the 15th day of gestation, expression is restricted largely to the liver, the bone forming regions of the jaw, the aortic endothelium, and the nasopharynx: a pattern that is maintained until just prior to birth. Postnatally, expression shifts to the red pulp of the spleen and the thymic medulla. Belongs to the SEC6 family. Truncated N-terminus.
