sulp-2 encodes one of eight C. elegans members of the sulfate permease family of anion transporters; by homology, SULP-2 is predicted to function as an anion transporter that regulates cellular pH and volume via transmembrane movement of electrolytes and fluids and when expressed in Xenopus oocytes, SULP-2 does exhibit modest uptake of sulfate; a SULP-2::GFP fusion is expressed in the intestine and rectal gland cells, where it localizes to the basolateral membrane and in cephalic and deirid neurons, where it localizes to sensillar endings.
Enables sulfate transmembrane transporter activity. Predicted to be involved in inorganic anion transmembrane transport and organic anion transport. Located in basolateral plasma membrane and non-motile cilium. Expressed in dopaminergic neurons and intestine. Human ortholog(s) of this gene implicated in several diseases, including Pendred Syndrome; autosomal recessive nonsyndromic deafness (multiple); and calcium oxalate nephrolithiasis. Is an ortholog of several human genes including SLC26A1 (solute carrier family 26 member 1); SLC26A3 (solute carrier family 26 member 3); and SLC26A4 (solute carrier family 26 member 4).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
