Summaries for CA8 Gene

Entrez Gene Summary for CA8 Gene

  • 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for CA8 Gene

CA8 (Carbonic Anhydrase VIII) is a Protein Coding gene. Diseases associated with CA8 include cerebellar ataxia and mental retardation with or without quadrupedal locomotion 3 and cerebellar hypoplasia and mental retardation with or without quadrupedal locomotion 1. Among its related pathways are Nitrogen metabolism. GO annotations related to this gene include carbonate dehydratase activity. An important paralog of this gene is CA14.
