Abstract:
| Five members of the RecQ helicase family, RECQL, WRN, BLM, RECQL4 and RECQL5 have been identified in humans. WRN and BLM have been demonstrated to be the responsible genes in Werner and Bloom syndromes, respectively. RECQL4 (RecQ helicase protein-like 4) was identified as a fourth member of the human RecQ helicase family bearing the helicase domain, and it was subsequently shown to be the responsible gene in Rothmund-Thomson syndrome. Here, we isolated mouse RECQL4 and determined the DNA sequence of full-length cDNA as well as the genome organization and chromosome locus. The mouse RECQL4 consists of 3651 base pairs coding 1216 amino acid residues and shares 63.4% of identical and 85.8% of homologous amino acid sequences with human RECQL4. The RECQL4 gene was localized to mouse chromosome 15D3 distal-E1 and rat chromosome 7q34 proximal. They were mapped in the region where the conserved linkage homology has been identified between the two species. Twenty-two exons dispersed over 7 kilo base pairs and all of the acceptor and donor sites for splicing of each exon conformed to the GT/AG rule. Our observations regarding mouse RECQL4 gene will contribute to functional studies on the RECQL4 products. |
