The surface of the starfish oocyte is thought to carry receptors for 1-methyladenine (1-MA)1,2, which induces maturation division by some mechanism which is at present little understood. Using α-(1→6)-heterogalactan (HGaln) and α-(1→6)-galacto-oligosaccharides, which strongly inhibit the induction of maturation division by 1-MA, we have now obtained evidence that the receptor for HGaln is on the cell surface. We found that in the presence of HGaln, 1-Ma did not activate the cell surface.
