Myelin, the insulating sheath made by extensive plasma membrane wrappings is dependent on the presence of highly adhesive molecules that keep the two sides of the membrane in tight contact. The Po glycoprotein (Po) is the major component of the peripheral nervous system (PNS) myelin of mammals. The exact role that Po protein has played in the evolution of myelin is still unclear, but several phylogenetic observations point to it as a crucial component in the development of myelin as a multi-lamellar membrane structure. Sharks, which appeared in evolution about 400 million years ago, are the first fully myelinated organisms. In this study we set out to investigate the expression pattern of shark myelin Po as a way of understanding how it might have played a role in the evolution of myelin in the central nervous system. We found that shark have more than two isoforms (32, 28 and 25kD), and that some of these might not be fully functional because they lack the domains known for Po homophilic adhesion.
