Involved in teeth and skeletal development (PubMed:29878199). Has an essential role in the biosynthesis and trafficking of glycosaminoglycans and glycoproteins to produce a proper functioning extracellular matrix (By similarity). Required for extracellular matrix mineralization (PubMed:29878199). Also involved in the regulation of cellular calcium homeostasis (By similarity). Does not show transport activity towards bile acids or steroid sulfates. Morphants have reduced head and eyes, a curled body, tooth cartilage that is bent downwards, reduced Meckel cartilage, absence of the fourth ceratobranchial cartilage, shortened or absent palate cartilage, widened palatal skeleton, reduced cleithrum, notochord, and lack of bone mineralization. Belongs to the bile acid:sodium symporter (BASS) (TC 2.A.28) family.
