Summary: Predicted to enable carbonate dehydratase activity. Acts upstream of or within morphogenesis of an epithelium and secretion. Predicted to be located in basolateral plasma membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including central nervous system; early embryo; genitourinary system; gut; and heart.

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.
