Keratin

Introduction: Keratin

Description of Keratin

Keratin: family of cystine-rich proteins that tend to aggregate in side-to- side fashion, forming tough filaments or sheets; main constituent of intermediate filaments in epidermal tissues.
Source: CRISP

Keratin: A class of fibrous proteins or scleroproteins that represents the principal constituent of EPIDERMIS; HAIR; NAILS; horny tissues, and the organic matrix of tooth ENAMEL. Two major conformational groups have been characterized, alpha-keratin, whose peptide backbone forms a coiled-coil alpha helical structure consisting of TYPE I KERATIN and a TYPE II KERATIN, and beta-keratin, whose backbone forms a zigzag or pleated sheet structure. alpha-Keratins have been classified into at least 20 subtypes. In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.
