Abstract
Synopsis: Myelin was isolated from the brain of a coelacanth. Its protein components were separated by polyacrylamide gel electrophoresis in the presence of sodium dodecylsulfate (SDS-PAGE). A protein component of 25000 Dalton was predominant; it was not glycosylated but reacted moderately with anti-mammalian CNS myelin proteolipid protein (PLP) antibodies and weakly with anti-lungfish CNS myelin glycosylated proteolipid protein (gPLP) antibodies. A component equivalent to mammalian DM-20 was not detectable. Presumably due to autolysis myelin basic protein (MBP) was not discernible by protein staining but showed up as a single band of 17000 Dalton with anti-mammalian MBP antibodies. Wolfgram protein (WP) was not present upon immunoblotting and the values for the myelin-specific 2′, 3′-cyclic nucleotide 3′-phosphodiesterase (CNPase) were extremely low. These results question a chondrichthyan association of the coelacanth but are strongly in favor of an Actinistia-Tetrapoda sister group relationship, with Dipnoi being most closely related to that combined group.

Presumably due to autolysis myelin basic protein (MBP) was not discernible by protein staining but showed up as a single band of 17000 Dalton with anti-mammalian MBP antibodies. Wolfgram protein (WP) was not present upon immunoblotting and the values for the myelin-specific 2′, 3′-cyclic nucleotide 3′-phosphodiesterase (CNPase) were extremely low. These results question a chondrichthyan association of the coelacanth but are strongly in favor of an Actinistia-Tetrapoda sister group relationship, with Dipnoi being most closely related to that combined group.</abstract><relatedItem type="host"><titleInfo><title>Environmental Biology of Fishes</title></titleInfo><titleInfo type="abbreviated"><title>Environ Biol Fish</title></titleInfo><genre type="journal" displayLabel="Archive Journal"></genre><originInfo><dateIssued encoding="w3cdtf">1991-09-01</dateIssued><copyrightDate encoding="w3cdtf">1991</copyrightDate></originInfo><subject><genre>Environment</genre><topic>Hydrobiology</topic><topic>Zoology</topic><topic>Animal Systematics/Taxonomy/Biogeography</topic><topic>Environment, general</topic><topic>Nature Conservation</topic></subject><identifier type="ISSN">0378-1909</identifier><identifier type="eISSN">1573-5133</identifier><identifier type="JournalID">10641</identifier><identifier type="IssueArticleCount">31</identifier><identifier type="VolumeIssueCount">4</identifier><part><date>1991</date><detail type="volume"><number>32</number><caption>vol.</caption></detail><detail type="issue"><number>1-4</number><caption>no.</caption></detail><extent unit="pages"><start>131</start><end>143</end></extent></part><recordInfo><recordOrigin>Kluwer Academic Publishers, 1991</recordOrigin></recordInfo></relatedItem><identifier type="istex">731C7B7ED94487D4B28748C6D2297628C3177AA6</identifier><identifier type="DOI">10.1007/BF00007449</identifier><identifier type="ArticleID">BF00007449</identifier><identifier type="ArticleID">Art8</identifier><accessCondition type="use and reproduction" contentType="copyright">Kluwer Academic Publishers, 1991</accessCondition><recordInfo><recordContentSource>SPRINGER</recordContentSource><recordOrigin>Kluwer Academic Publishers, 1991</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
