Protein

Carbonic anhydrase-related protein

Gene

CA8

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Does not have a carbonic anhydrase catalytic activity.

Caution

Although it belongs to the alpha-carbonic anhydrase family, Arg-116 is present instead of the conserved His which is a zinc-binding residue. It is therefore expected that this protein lacks carbonic anhydrase activity.Curated
