abstractText | The SNF2 gene family consists of a large group of proteins involved in transcriptional regulation, maintenance of chromosome integrity, and various aspects of DNA repair. We cloned a novel SNF2 family human cDNA, with sequence identity to the Escherichia coli RNA polymerase-binding protein HepA and named the human hepA-related protein (HHARP/SMARCAL1). In addition, the mouse ortholog (Mharp/Smarcal1) was cloned, and the Caenorhabditis elegans ortholog (CEHARP) was identified in the GenBank database. Phylogenetic analysis indicates that the HARP proteins share a high level of sequence similarity to the seven motif helicase core region (SNF2 domain) with identifiable orthologs in other eukaryotic species, except for yeast. Purified His-tagged HARP/SMARCAL1 protein exhibits single-stranded DNA-dependent ATPase activity, consistent with it being a member of the SNF2 family of proteins. Both the human and the mouse genes consist of 17 exons and 16 introns. The human gene maps to chromosome 2q34-q36, and the mouse gene is localized to the syntenic region of chromosome 1 (between markers Gls and Acrg). HARP/SMARCAL1 transcripts are ubiquitously expressed in human and mouse tissues, with testis presenting the highest levels of mRNA expression in humans. |
