CGDB: Circadian Gene DataBase

CGDB: Circadian Gene DataBase

General Information

1. CGDB: Circadian Gene DataBase
2. This is a circadian gene database.
   1. The database includes circadian gene DNA and protein sequences, model organisms specific to each circadian gene, clear descriptions of the circadian gene functions, and circadian gene tags specific to this database and other databases (http://cgdb.biocuckoo.org/view.php?id=021036).
   2. Circadian Gene DataBase is a secondary source of data.
      • The data has been curated.
      • The database utilizes human curation.
      • The database utilizes in house staff.
      • https://academic.oup.com/nar/article/45/D1/D397/2333922/CGDB-a-database-of-circadian-genes-in-eukaryotes.
3. The Cuckoo Workgroup Maintains the database.
   • This is a private organization.
   • This organization consists of a small lab group.
   • http://www.biocuckoo.org/people.php.
4. This organization is funded by:
   • National Basic Research Program
   • Natural Science Foundation of China
   • International Science & Technology Cooperation Program of China
   • Natural Science Foundation of Anhui Province
   • National Natural Science Foundation of China
   • https://academic.oup.com/nar/article/45/D1/D397/2333922/CGDB-a-database-of-circadian-genes-in-eukaryotes.

Quality of Science

1. Content Domain:
   • The database contains over 72,800 experimentally verified genes with rhythmic expression (http://cgdb.biocuckoo.org/index.php).
   • The database owners point out that there is a lack of comprehensive database which cycle genes across phyla and these owners claim to fill that need (https://academic.oup.com/nar/article/45/D1/D397/2333922/CGDB-a-database-of-circadian-genes-in-eukaryotes).
2. The species covered in the database include plants, animals, and fungi (http://cgdb.biocuckoo.org/browse.php).
3. Is the database content timely?
   • There is a need in the scientific community for this database at this time due to the fact that disruptions in circadian rhythms have been possibly entwined with diseases and disorders such as but not limited to psychiatric disorders and cancer. (Info found here: https://academic.oup.com/nar/article/45/D1/D397/2333922/CGDB-a-database-of-circadian-genes-in-eukaryotes#51198539)
   • This content is covered by other databases already, but not a comprehensive database for the circadian genes across phyla. (Info found here: https://academic.oup.com/nar/article/45/D1/D397/2333922/CGDB-a-database-of-circadian-genes-in-eukaryotes#51198539)
   • The database first went online in 2004. (Info found here: https://academic.oup.com/nar/article/45/D1/D397/2333922/CGDB-a-database-of-circadian-genes-in-eukaryotes#51198539)
   • The database is updated when new cycling genes are experimentally characterized. It appears that the database is updated monthly. (Info found here: https://academic.oup.com/nar/article/45/D1/D397/2333922/CGDB-a-database-of-circadian-genes-in-eukaryotes#51198539
   • The database was last updated October 1, 2017. (Info found here: http://cgdb.biocuckoo.org/index.php)

General Utility

1. Are there links to other databases?
   • This database contains links to other databases:
   • http://circadb.hogeneschlab.org/
   • http://www.wgpembroke.com/shiny/SCNseq/
   • https://www3.nd.edu/~bioclock/
   • http://circadiomics.igb.uci.edu/
   • http://diurnal.mocklerlab.org/
   • http://www.bioinfo.mpg.de/euclis/
   • http://www.dbcryptochrome.org/
   • http://www.ensembl.org/index.html
   • Important note: not all of these links are successful(Info found here: http://cgdb.biocuckoo.org/links.php
2. Is it convenient to browse the data?
   • The data is fairly convenient to browse.
3. Is it convenient to download the data?
   • The convenience of data depends on your preference. When downloading the data a new browser tab is opened with all of the protein sequences listed for each gene which is fairly easy to read. The only con is that you will have to copy and paste the data into another file to store it.
   • All downloads come in the .txt format (http://cgdb.biocuckoo.org/download.php).
   • A TXT file is a standard text document and does not have any formatted text (https://fileinfo.com/extension/txt).
