Figure 1From: Protogenin, a new member of the immunoglobulin superfamily, is implicated in the development of the mouse lower first molarPrtg has a characteristic domain structure and putative glycosylation sites in the extracellular region. The Prtg protein contains a signal peptide, Ig domains, five fibronectin-type III (FNIII) repeats, a single transmembrane (TM), and a cytoplasmic domain (CD). The structure indicates a high similarity to Nope. The circles indicate glycosylated sites.Back to article page
