Background

AMN (Amnionless) is a 45-49 kDa glycoprotein that is expressed by three cell types in mouse; extraembryonic visceral endoderm, proximal tubule renal epithelium, and absorption intestinal epithelium. AMN is required for gastrulation in rodent (but not human), and participates in Vitamin B12 absorption in the gut. In particular, AMN forms a membrane complex with Cubilin, promoting its proper orientation in the membrane and subsequent binding to the Intrinsic factor: VitB12 complex. Mature mouse AMN is a 439 amino acid (aa) type I transmembrane protein. It contains a 343 aa extracellular region (aa 20-362) that possesses one VWFC domain (aa 203‑254), and a 75 aa cytoplasmic tail. In human, AMN may undergo cleavage to generate a 35 kDa soluble fragment. Over aa 20-362, mouse AMN shares 92% and 67% aa sequence identity with rat and human AMN, respectively.
