Gene Gene information from NCBI Gene database.
Entrez ID 125115
Gene name Keratin 40
Gene symbol KRT40
Synonyms (NCBI Gene)
CK-40K40KA36
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
