Characterization of human Enah gene

Enabled homolog (Enah) is a mammalian ortholog of Drosophila Enabled (Ena), which is genetically linked to the Drosophila Abl tyrosine phosphorylation signaling cascade and is required for normal neural development. Vertebrates have three Ena-related genes: Enah, VASP (vasodilator-stimulated phosphoprotein) and Ena/VASP like (EVL). These genes play an important role in linking signal transduction pathways to localized remodeling of the actin cytoskeleton. We isolated and sequenced a cDNA encoding human Enah. Comparison of the amino acid sequences of mouse (Mus musculus) and human (Homo sapiens) species shows 86.6% identity. The human protein appears longer than the mouse and additional amino acids are concentrated in a region containing repeats of the amino acid sequence LERER. The complete gene is about 157 kb and consists of 14 exons. Analysis of multiple tissue northern blot revealed a major transcript of about 4.8 kb in all tissue examined. Alternatively spliced isoforms were isolated by RT-PCR. The gene is differentially expressed and to gain insight factors affecting its expression we cloned and preliminarily characterized human Enah gene promoter.
