Cloning and characterization of RECQL, a potential human homologue of the Escherichia coli DNA helicase RecQ.
A potential human DNA helicase, RECQL, was partially purified from HeLa cells, and a cDNA encoding this protein was subsequently cloned from a HeLa library. The RECQL cDNA contains a protein coding region of 1977 base pairs, and encodes a 659-amino-acid polypeptide with a predicted M(r) 72,000. This predicted protein sequence contains several domains that have extensive sequence identity with s...
متن کاملRECQL: a DNA helicase in breast cancer
We recently reported that mutations in the RECQL gene are associated with an increased risk of breast cancer [1]. We identified recurrent RECQL mutations in two founder populations in Poland and Quebec, Canada, and we found that these mutations increase the risk of breast cancer by 5-fold among unselected cases from Poland and by 16-fold among higher-risk cases in Quebec. The association of REC...
متن کاملRecQ-like helicases: the DNA replication checkpoint connection.
The eukaryotic homologues of the Escherichia coli RecQ DNA helicase play conserved roles in the maintenance of genome stability. Results obtained in yeast and mammalian systems are beginning to form a coherent picture about what these helicases do to ensure normal cell division and why humans who lack these enzymes are cancer prone. Recent data suggest that the yeast enzyme Sgs1p, as well as tw...
متن کاملOrganization of chromosome ends in Ustilago maydis. RecQ-like helicase motifs at telomeric regions.
In this study we have established the structure of chromosome ends in the basidiomycete fungus Ustilago maydis. We isolated and characterized several clones containing telomeric regions and found that as in other organisms, they consist of middle repeated DNA sequences. Two principal types of sequence were found: UTASa was highly conserved in nucleotide sequence and located almost exclusively a...
متن کاملEvolution of the RECQ family of helicases: A drosophila homolog, Dmblm, is similar to the human bloom syndrome gene.
Several eukaryotic homologs of the Escherichia coli RecQ DNA helicase have been found. These include the human BLM gene, whose mutation results in Bloom syndrome, and the human WRN gene, whose mutation leads to Werner syndrome resembling premature aging. We cloned a Drosophila melanogaster homolog of the RECQ helicase family, Dmblm (Drosophila melanogaster Bloom), which encodes a putative 1487-...
