FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an astacin-like, zinc-dependent, metalloprotease that belongs to the peptidase M12A family. This protease processes procollagen C-propeptides, such as chordin, pro-biglycan and pro-lysyl oxidase. Studies in mice suggest that this gene plays multiple roles in the development of mammalian heart, and is essential for the formation of the interventricular septum. Allelic variants of this gene are associated with atrial septal defect type 6. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

PHENOTYPE: Homozygous null mice are embryonic lethal with death at midgestation from cardiac failure. Cardiac defects include incomplete formation of the ventricular septum and abnormal positioning of the heart and aorta. [provided by MGI curators]
