Hpx Gene Summary [Rat]
Predicted to enable heme transmembrane transporter activity and metal ion binding activity. Predicted to be involved in heme metabolic process. Predicted to act upstream of or within several processes, including positive regulation of immune effector process; positive regulation of type II interferon-mediated signaling pathway; and positive regulation of tyrosine phosphorylation of STAT protein. Predicted to be active in extracellular space. Orthologous to human HPX (hemopexin). [provided by Alliance of Genome Resources, Apr 2025]

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 Hpx often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
