DNA methyltransferase 3A

DNA methyltransferase 3A is a redirect to the main article titled DNA (cytosine-5)-methyltransferase 3A . This redirect exists to accommodate alternative capitalisation of the enzyme’s name while maintaining alignment with Wikipedia naming conventions .

Purpose and context

This redirect falls under the category of redirects from other capitalisations , which exist to handle variations in letter casing while ensuring proper connection to the correctly capitalised article title. The DNA methyltransferase family of enzymes plays critical roles in epigenetic regulation , with DNA methyltransferase 3A (DNMT3A) specifically involved in de novo DNA methylation during embryonic development.

The capitalization “methyltransferase” rather than “methylTransferase” follows standardized IUPAC nomenclature for enzymes, where the lowercase “t” reflects the linguistic structure rather than biochemical hierarchy. This convention aligns with Wikipedia’s preference for scientific naming conventions .

Capitalization conventions on Wikipedia

Wikipedia maintains strict capitalization rules to ensure consistency across articles:

1. Article titles: Follow sentence case unless proper nouns or specific naming conventions dictate otherwise
2. Scientific names: Adhere to International Union of Biochemistry guidelines for enzyme nomenclature
3. Redirect structure: Accommodates common misspellings and capitalization variants to improve search functionality

When editors encounter incorrect capitalization in links, they should:

• Update links to point directly to the properly capitalized article
• Tag miscapitalized redirects in the main namespace using the {{R from miscapitalisation }} template
• Use {{R from modification }} for non-mainspace capitalization variants

Technical implementation

This redirect functions through Wikipedia’s soft redirect system, which automatically connects users to the target article without creating a separate database entry . The MediaWiki software handles these redirects by:

1. Parsing the requested URL
2. Checking the redirect table
3. Serving the target article’s content with a header indicating the redirection

For search engine optimization , redirect pages contain:

• A brief explanatory text
• Relevant category links
• Maintenance templates when applicable

Maintenance considerations

Editors should periodically check redirect pages like this one to:

1. Verify the target article remains the most appropriate destination
2. Ensure no circular redirects exist
3. Confirm compliance with current Wikipedia style guidelines
4. Remove redundant redirects when multiple capitalization variants exist

In the specific case of enzyme nomenclature redirects, cross-referencing with the BRENDA database and UniProt entry Q9Y6K1 can help validate the preferred capitalization format.
