Predicted to enable choline transmembrane transporter activity and thiamine pyrophosphate transmembrane transporter activity. Predicted to be involved in several processes, including acetylcholine biosynthetic process; organic cation transport; and sensory organ development. Predicted to be located in apical plasma membrane. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 72. Orthologous to human SLC44A4 (solute carrier family 44 member 4). [provided by Alliance of Genome Resources, Apr 2022]
