WebSEMA7A is a membrane-bound semaphorin that associates with cell surfaces via a glycosylphosphatidylinositol (GPI) linkage. SEMA7A is also known as the John-Milton-Hagen (JMH) blood group antigen, an 80-kD glycoprotein expressed on activated lymphocytes and erythrocytes. [supplied by OMIM] [5] SEMA7A is expressed in various adult tissues such … WebThis last observation can be explained by the fact that Semaphorin 3E is highly-expressed in the somites and normally acts as a repulsive signal for branching vessels (Gu et al., 2005). Consistent with this model, knockout of Semaphorin 3E eliminated the repulsive activity and allowed vessels to extend ectopically into the somites.
