Description

General description

Carbonic anhydrase 1 (CA1) is a cytosolic protein, encoded by the gene mapped to human chromosome 8q21.2.[64} The encoded protein belongs to the carbonic anhydrase (CA) family. CA1 is highly expressed in blood. Its expression is also found in spinal cord motor neurons, intestinal, vascular, corneal epithelia, synovium and cardiac capillary endothelial cells.

Carbonic anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide. They participate in a variety of biological processes, including respiration, calcification, acid-base balance, bone resorption, and the formation of aqueous humor, cerebrospinal fluid, saliva, and gastric acid. They show extensive diversity in tissue distribution and in their subcellular localization. CA1 is closely linked to CA2 and CA3 genes on chromosome 8, and it encodes a cytosolic protein which is found at the highest level in erythrocytes. Variants of this gene have been described in some populations. Multiple alternatively spliced variants, encoding the same protein, have been identified. Transcript variants of CA1 utilizing alternative polyA_sites have been described in literature. (provided by RefSeq)

Biochem/physiol Actions

Carbonic anhydrase 1 (CA1) catalyzes the reversible hydration and dehydration reactions of CO2/ carbonic acid (H2CO3).[65} It plays a vital role in the transport of metal ions. In addition, it might also be involved in biomineralization and new bone formation. CA1 acts as an oncogene and leads to irregular cell calcification, apoptosis and migration in breast tumor tissues. Overexpression of the gene has been observed in serum of stage I non-small cell lung cancer (NSCLC) patients. It can be used as a potential biomarker for early diagnosis of NSCLC. Additionally, CA1 is also upregulated in amyotrophic lateral sclerosis (ALS) and is involved in motor neuron degeneration.
