Abstract

Our knowledge at present on the structure of acrosome-reaction inducing substance (ARIS) in the jelly coat of starfish eggs is summarized. ARIS ia a proteoglycan-like molecule consisting of very long, linear, and highly sulfated glycans and three ARIS proteins, ARIS1-3. Detailed structures of the major glycan of ARIS and of ARIS1-3 are discussed. 3D-models of ARIS glycans are also presented. Phylogenetic distribution of ARIS proteins and/or genes indicates that ARIS genes are well preserved from the Ctenophore to Cephalochordata. In the Echinodermata, ARIS1-3 and ARIS genes were detected in all classes except for sea urchins.
