Identification
HMDB Protein ID CDBP01911
Secondary Accession Numbers Not Available
Name Haptoglobin
Description Not Available
Synonyms
  1. Haptoglobin alpha chain
  2. Haptoglobin beta chain
Gene Name HP
Protein Type Enzyme
Biological Properties
General Function Involved in hemoglobin binding
Specific Function Haptoglobin combines with free plasma hemoglobin, preventing loss of iron through the kidneys and protecting the kidneys from damage by hemoglobin, while making the hemoglobin accessible to degradative enzymes
