Summary: Enables carbonate dehydratase activity. Involved in several processes, including estrous cycle; positive regulation of bone resorption; and positive regulation of osteoclast differentiation. Located in several cellular components, including apical part of cell; basolateral plasma membrane; and microvillus. Human ortholog(s) of this gene implicated in autosomal recessive osteopetrosis 3 and osteopetrosis. Orthologous to human CA2 (carbonic anhydrase 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
