Identification
HMDB Protein ID CDBP02266
Secondary Accession Numbers Not Available
Name Carbonic anhydrase 4
Description Not Available
Synonyms
  1. CA-IV
  2. Carbonate dehydratase IV
  3. Carbonic anhydrase IV
Gene Name CA4
Protein Type Enzyme
Biological Properties
General Function Involved in carbonate dehydratase activity
Specific Function Reversible hydration of carbon dioxide. May stimulate the sodium/bicarbonate transporter activity of SLC4A4 that acts in pH homeostasis. It is essential for acid overload removal from the retina and retina epithelium, and acid release in the choriocapillaris in the choroid.
