Subcellular Location SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Lipid-anchor, GPI-anchor {ECO:0000250}. Note=Also released in the extracellular space. {ECO:0000269|PubMed:25156943}.
Modified Residue MOD_RES 46; /note=Phosphotyrosine; /evidence=ECO:0000250|UniProtKB:Q7TQ32
Post Translational Modification PTM: Autocatalytically cleaved at low pH; the two chains remain linked via two disulfide bonds (PubMed:25156943). Also proteolytically processed by TMPRSS6, several fragments being released in the extracellular space; regulates HJV activity in BMP signaling and thefore iron homeostasis (PubMed:18976966, PubMed:25156943). {ECO:0000269|PubMed:18976966, ECO:0000269|PubMed:25156943}.
