Summary: Enables BMP binding activity and coreceptor activity. Involved in intracellular iron ion homeostasis and negative regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including BMP signaling pathway; multicellular organismal-level iron ion homeostasis; and negative regulation of BMP signaling pathway. Located in cell surface and extracellular space. Is expressed in several structures, including gonad; musculature; submandibular gland; trunk mesenchyme; and yolk sac. Used to study hemochromatosis type 2A. Human ortholog(s) of this gene implicated in hemochromatosis and hemochromatosis type 2A. Orthologous to human HJV (hemojuvelin BMP co-receptor).

Hjv was significantly downregulated in the muscles of mdx mice as well as in those of aged mice. Overexpression of Hjv rescued dystrophic and age-related muscle wasting. Mechanistically, loss of Hjv promoted activation of Smad3 signalling induced by TGF-beta1, whereas Hjv overexpression inhibited TGF-beta1/Smad3 signalling by directly interacting with TbetaRII on the muscle membrane.

The results provide support for the interaction between TMPRSS6 and hemojuvelin in vivo; they also suggest that hemojuvelin could be cleaved by another as yet unknown protease in the absence of functional TMPRSS6.

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.
