Facts about Haptoglobin-related protein.
Binds hemoglobin with high affinity and may contribute to the lack of cell-free hemoglobin to allow hepatic recycling of heme iron. .

In adult liver the amount of HPR mRNA is at the lower limit of detection, therefore the extent of its expression is at most less than 1000-fold that of the HP1F gene. No HPR mRNA can be detected in fetal liver. Expressed in Hep-G2 and leukemia MOLT-4 cell lines.
Secreted. Secreted into blood plasma and associated with subtypes of high density lipoproteins (HDL).
