Summary: Predicted to enable BMP binding activity; coreceptor activity; and transferrin receptor binding activity. Predicted to contribute to BMP receptor activity. Predicted to be involved in several processes, including negative regulation of transcription by RNA polymerase II; protein autoprocessing; and transforming growth factor beta receptor superfamily signaling pathway. Predicted to act upstream of or within multicellular organismal-level iron ion homeostasis; negative regulation of BMP signaling pathway; and positive regulation of transcription by RNA polymerase II. Located in basolateral plasma membrane. Human ortholog(s) of this gene implicated in hemochromatosis and hemochromatosis type 2A. Orthologous to human HJV (hemojuvelin BMP co-receptor).

Phagocytosis upregulates hepcidin-gene expression and downregulates Hjv- and Fpn-1-gene expression within the liver.
Title: Phagocytosis of gadolinium chloride or zymosan induces simultaneous upregulation of hepcidin- and downregulation of hemojuvelin- and Fpn-1-gene expression in murine liver.
The results suggest that the HJV-neogenin interaction is required for the BMP-mediated induction of hepcidin expression when HJV is expressed.
Title: Hemojuvelin-neogenin interaction is required for bone morphogenic protein-4-induced hepcidin expression.
hemojuvelin(HFE2)& transferrin receptor type 2 were predominantly localized to hepatocyte basolateral membrane domain; localization of HFE2 & TfR2 at the same membrane domain renders a functional interaction of these proteins in iron homeostasis possible

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
