Me ...	This entry represents the small N-terminal three helical bundle domain found at the N-terminus of proteins in the Repulsive Guidance Molecule (RGM) family, which is involved in various functions related to nervous system development and signaling. Members of this family act as bone morphogenetic protein (BMP) coreceptors, enhancing BMP signaling pathways. They play crucial roles in regulating neural tube closure, inhibiting neurite outgrowth, and promoting neuronal adhesion. Additionally, they are involved in the regulation of iron homeostasis through the modulation of hepcidin expression. The RGM family also influences axon guidance and synapse formation, contributing to the patterning of the developing nervous system.	Domain
