CA VIII Polyclonal Antibody

The protein encoded by CA8 (carbonic anhydrase 8) 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. Mutations in CA8 are associated with cerebellar ataxia, mental retardation, and dysequilibrium syndrome 3 (CMARQ3). Polymorphisms in CA8 are associated with osteoporosis, and overexpression of CA8 in osteosarcoma cells suggests an oncogenic role. Alternative splicing results in multiple transcript variants.
