Drosophila ash2 belongs to the trithorax (trx) gene family. The ash2 product positively regulates expression of homeotic selector genes, and is implicated in early development and formation of various disc patterns in the fruit fly. Through large-scale sequencing of human genomic DNA coupled with in silico gene trapping, we identified a gene (ASH2L) on chromosome 8p11.2 whose predicted product was highly homologous to ash2, characterized it, and identified its mouse counterpart. The human ash2 cDNA is 2368 bp long, encoding 628 amino acids. The 16-exon gene spans more than 34 kb of genomic DNA between STS markers WI-9207 (centromere) and AFMA295ZD5 (telomere) on chromosome 8, with transcription oriented telomere to centromere. The ash2 genes are highly conserved among different species, including C. elegans and yeast. The presence of a conserved bipartite nuclear localization signal and a PHD finger motif in the human ash2 gene suggests that the gene product would function as a transcriptional regulator in humans, as its homologue does in Drosophila.
