Alagille syndrome is an autosomal dominant multisystem disorder defined clinically by hepatic bile duct paucity and cholestasis in association with cardiac, skeletal, and ophthalmologic manifestations. There are characteristic facial features and less frequent clinical involvement of the renal and vascular systems.<ref>PMID:9207788</ref> <ref>PMID:9207787</ref> <ref>PMID:9585603</ref> <ref>PMID:10220506</ref> <ref>PMID:10533065</ref> <ref>PMID:11058898</ref> <ref>PMID:11157803</ref> <ref>PMID:11139247</ref> <ref>PMID:11180599</ref> <ref>PMID:12442286</ref> <ref>PMID:12497640</ref> <ref>PMID:15712272</ref> <ref>PMID:16575836</ref> Defects in JAG1 are a cause of tetralogy of Fallot (TOF) [MIM:[http://omim.org/entry/187500 187500]]. TOF is a congenital heart anomaly which consists of pulmonary stenosis, ventricular septal defect, dextroposition of the aorta (aorta is on the right side instead of the left) and hypertrophy of the right ventricle. This condition results in a blue baby at birth due to inadequate oxygenation. Surgical correction is emergent.<ref>PMID:9207787</ref> <ref>PMID:11152664</ref> | ||

| + | ABSTRACT: BACKGROUND: Notch signaling drives developmental processes in all metazoans. The receptor binding region of the human Notch ligand Jagged-1 is made of a DSL (Delta/Serrate/Lag-2) domain and two atypical epidermal growth factor (EGF) repeats encoded by two exons, exon 5 and 6, which are out of phase with respect to the EGF domain boundaries. RESULTS: We determined the 1H-NMR solution structure of the polypeptide encoded by exon 6 of JAG1 and spanning the C-terminal region of EGF1 and the entire EGF2. We show that this single, evolutionary conserved exon defines an autonomous structural unit that, despite the minimal structural context, closely matches the structure of the same region in the entire receptor binding module. CONCLUSIONS: In eukaryotic genomes, exon and domain boundaries usually coincide. We report a case study where this assertion does not hold, and show that the autonomously folding, structural unit is delimited by exon boundaries, rather than by predicted domain boundaries. | ||
