The protein encoded by this gene is one of several isozymes of carbonic anhydrase. This protein is found only in salivary glands and saliva and protein may play a role in the reversible hydratation of carbon dioxide though its function in saliva is unknown. [provided by RefSeq, Jul 2008]
A study in dogs demonstrated that the CA6 mRNA was detected in only 1 out of 20 canine saliva samples and was found in 9 out of 10 canine whole blood samples, showing it was unsuitable for saliva identification due to its low detection rate in saliva and expression in blood [Nakanishi et al. DOI:10.1007/S00414-016-1391-7]. A separate review in humans identifies the CA6 as a salivary protein detectable via mass spectrometry, classifying it as a proteomic marker with applications for indicating physiological and pathological states [Kumar et al. DOI:10.1016/J.Jflm.2025.103044].
