Bioinformatic analysis of pathogenic missense mutations of activin receptor like kinase 1 ectodomain.

ABSTRACT: Activin A receptor, type II-like kinase 1 (also called ALK1), is a serine-threonine kinase predominantly expressed on endothelial cells surface. Mutations in its ACVRL1 encoding gene (12q11-14) cause type 2 Hereditary Haemorrhagic Telangiectasia (HHT2), an autosomal dominant multisystem vascular dysplasia. The study of the structural effects of mutations is crucial to understand their pathogenic mechanism. However, while an X-ray structure of ALK1 intracellular domain has recently become available (PDB ID: 3MY0), structure determination of ALK1 ectodomain (ALK1(EC)) has been elusive so far. We here describe the building of a homology model for ALK1(EC), followed by an extensive bioinformatic analysis, based on a set of 38 methods, of the effect of missense mutations at the sequence and str
