CA8
Carbonic anhydrase-related protein is an protein that in humans is encoded by the CA8 gene.[5][6] The CA8 protein lacks the catalytic activity of other carbonic anhydrase enzymes.[7] A rare, autosomal recessive form of cerebellar ataxia known as "cerebellar ataxia, mental retardation, and dysequilibrium syndrome 3" (CAMRQ3) is caused by mutations in the CA8 gene.[7][8]

Function
The protein encoded by this gene was initially named CA-related protein because of sequence similarity to other known carbonic anhydrase genes. However, the gene product lacks carbonic anhydrase activity (i.e., the reversible hydration of carbon dioxide). The gene product continues to carry a carbonic anhydrase designation based on clear sequence identity to other members of the carbonic anhydrase gene family. The absence of CA8 gene transcription in the cerebellum of the lurcher mutant in mice with a neurologic defect suggests an important role for this acatalytic form.[6]
Interactions
CA8 has been shown to interact with ITPR1.[9]
gollark: There are many vaguely interesting fields, but I have no idea if there's any one thing I care about enough to specialise in for several years.
gollark: Yes, I worry about that too.
gollark: I got bored and started looking at university league tables and course lists and stuff recently.
gollark: I see. You already know it somewhat, clearly.
gollark: Anyway, I *did* GCSEs this year, I *am doing* A levels next school year and for two years after that, and I *am probably* going to university of some sort after that (I've been overresearching that out of böredom).
