  • Title: [Cloning and structural characteristics of human hair keratin genes rich in sulfur].
    Author: Zhumabaeva BD, Gening LV, Gazarian KG.
    Journal: Mol Biol (Mosk); 1992; 26(4):813-20. PubMed ID: 1279380.
    Abstract:
    Two human genomic genes for the hair high-sulphur keratins were for the first time cloned in a 15 kb fragment. The primary structures of the coding regions of the genes and their 5'- and 3'-flanks were determined. In the 5'-flanking region, TATA boxes, initiating codons and a 18 nucleotide sequence, previously described in sheep keratin genes and designated as "the matrix-specific" sequence was revealed. Basing on the nucleotide sequences, the encoded amino acid sequences of the high-sulphur keratins were determined for the first time. The suggested functional role of the structural elements (regions) revealed in the proteins primary structure and problems concerning their evolution tendencies are discussed.
