Glycosyltrasferase activity in developing sea-urchin embryos.
The developmental course of activity changes of 4 endogenous membrane glycosyltransferases: UDP-glucose : glycosyltrasferase, UDP-galactose : glycosyltransferase, GDP-mannose: glycosyltransferase, and UD-PN-acetylglucosamine : glycosyltransferase was determined in various stages of developing sea-urchin embryos from unfertilized eggs up to the 16-cell stage. The results show that there is a 2-f...

The developmental course of activity changes of 4 endogenous membrane glycosyltransferases : UDP-glucose : glycosyltransferase, UDP-galactose : glycosyltransferase, GDP-mannose: glycosyltransferase, and UD-PiV-acetylglucosamine : glycosyltransferase was determined in various stages of developing sea-urchin embryos from unfertilized eggs up to the 16-cell stage. The results show that there is a ...
متن کاملCompetitive titration in living sea urchin embryos of regulatory factors required for expression of the Cyllla actin gene
Previous studies have located some twenty distinct sites within the 2.3 kb 5' regulatory domain of the sea urchin CyHIa cytoskeletal actin gene, where there occur in vitro high-specificity interactions with nuclear DNA-binding proteins of the embryo. This gene is activated in late cleavage, exclusively hi cells of the aboral ectoderm cell lineages. In this study, we investigate the functional i...

متن کاملPattern of Brachyury gene expression in starfish embryos resembles that of hemichordate embryos but not of sea urchin embryos
Echinoderms, hemichordates and chordates are deuterostomes and share a number of developmental features. The Brachyury gene is responsible for formation of the notochord, the most defining feature of chordates, and thus may be a key to understanding the origin and evolution of the chordates. Previous studies have shown that the ascidian Brachyury (As-T and Ci-Bra) is expressed in the notochord ...
