Hjv Gene Summary [Rat]
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).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Hjv often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
