This family represents the C-terminus of eukaryotic neogenin precursor proteins, which contains several potential phosphorylation sites [1]. Neogenin is a member of the N-CAM family of cell adhesion molecules (and therefore contains multiple copies of Pfam:PF00047 and Pfam:PF00041) and is closely related to the DCC tumour suppressor gene product - these proteins may play an integral role in regulating differentiation programmes and/or cell migration events within many adult and embryonic tissues [2].
