Carbonic Anhydrase 8 Protein, Human (His)

Carbonic Anhydrase VIII/CA8 Protein, Human (His) expresses in E. coli with a His tag at the N-terminus. Carbonic anhydrase 8 (CA8), an isozyme of α-carbonic anhydrases (CAs), is an allosteric inhibitor of inositol trisphosphate receptor-1 (ITPR1), which regulates neuronal intracellular calcium release^[1][2].

CA8 overexpression desensitizes neuronal cells to STS induced apoptotic stress and increases cell migration and invasion ability in neuronal cells. In addition, down-regulated CA8 decreases neuron mobility in neuronal cells and leads to abnormal calcium release in cerebellar granule neurons. Knockdown of the ca8 gene results in an abnormal movement pattern in zebrafish^[2].

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
