• Entrez ID: 3891
• Gene name: Keratin 85
• Gene symbol: KRT85
• Synonyms: ECTD4, HB5, Hb-5, K85, KRTHB5, hHb5
• Chromosome: 12
• Chromosome location: 12q13.13
• Summary: The protein encoded by this gene is a member of the keratin gene family. As a type II hair keratin, it is a basic protein which heterodimerizes with type I keratins to form hair and nails. The type II hair keratins are clustered in a region of chromosome
