Database Description

MAGEST is a database of maternal gene expression information for an Ascidian, Halocynthia roretzi. The ascidian has become an animal model in developmental biological research because it shows the simple developmental process and belongs to the one of chordate groups. We register some kinds of dataset with the MAGEST database, e.g., the 3Õ- and 5Õ- tag sequences from the fertilized egg cDNA library, the result of similarity search against the GenBank and the expression data from whole mount in situ hybridization. For the last two years, the data retrieval systems have been improved in several points and the tag sequence entries have increased to over 20,000 clones. Beside these data, we try to produce the amino acid fragment sequences predicted from the EST data set. Using these data from comprehensive view, we will get some new information of the gene functions. The MAGEST database is available through the www at

Recent Developments

Translated MAGEST is a database of the fragments of the amino acid sequence that are translated from MAGEST EST entries. To date, the about 3000 entries are registered in the Translated MAGEST.
