KRT25 (keratin 25)

Gene

• Entrez ID: 147183
• Gene name: Keratin 25
• Gene symbol: KRT25
• Synonyms (NCBI Gene): ARWH3, KRT24IRS1, KRT25A
• Disease Acronyms (UniProt): ARWH3
• Chromosome: 17
• Chromosome location: 17q21.2
• Summary: This gene encodes a member of the type I (acidic) keratin family, which belongs to the superfamily of intermediate filament (IF) proteins. Keratins are heteropolymeric structural proteins which form the intermediate filament. These filaments, along with a
