  • Title: Cloning the Drosophila homolog of the xeroderma pigmentosum complementation group C gene reveals homology between the predicted human and Drosophila polypeptides and that encoded by the yeast RAD4 gene.
    Author: Henning KA, Peterson C, Legerski R, Friedberg EC.
    Journal: Nucleic Acids Res; 1994 Feb 11; 22(3):257-61. PubMed ID: 8127661.
    Abstract:
    A human xeroderma pigmentosum group C (XPC) cDNA has been previously isolated by functional complementation (Legerski and Peterson, Nature, 359, 70-73, 1992). Sequence analysis did not reveal protein motifs which might suggest a possible biochemical function for the putative XPC protein. In order to identify functional domains in the translated XPC sequence the homologous gene from Drosophila melanogaster, designated XPCDM, was cloned by DNA hybridization. Sequence analysis of an apparently full-length cDNA revealed an open reading frame which can encode a predicted polypeptide of 1293 amino acids. Significant homology of the C-terminal 346 amino acids with both the human XPC and Saccharomyces cerevisiae Rad4 protein sequences is observed, suggesting that these proteins are functional homologs.
