aat-9 encodes an amino acid transporter catalytic subunit; AAT-9 lacks the conserved cysteine residue proposed to be essential for association with a glycoprotein subunit, and when expressed alone in Xenopus ooctyes, AAT-9 can localize to the cell surface and function as an aromatic amino acid exchanger that displays substrate-activated anion conductance; nevertheless, AAT-9 activity is enhanced by co-expression with the ATG-1 and ATG-2 glycoprotein subunits; an aat-9::gfp promoter fusion directs expression in anterior neurons, including some chemosensory neurons, as well as in some anterior body wall muscles.
Predicted to enable L-amino acid transmembrane transporter activity. Predicted to be involved in amino acid transmembrane transport. Located in cell surface. Expressed in body wall musculature and neurons.
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.
