This is a treatable gastrointestinal disease where dogs cannot absorb cobalamin, often causing them to be runty with poor energy levels. Genotyping was performed by restriction enzyme digestion of PCR amplicons. [8] Whereas, amnionless is an apical transmembrane protein which is expressed in both intestine and kidney, and it seems to assist the subcellular localization and endocytosis of the cubilin by binding to its amino-terminal residues.
