Summary: Predicted to enable potassium channel regulator activity; solute:sodium symporter activity; and transmembrane transporter binding activity. Involved in regulation of transporter activity. Acts upstream of or within several processes, including inositol metabolic process; myo-inositol transport; and positive regulation of reactive oxygen species biosynthetic process. Located in apical plasma membrane and basolateral plasma membrane. Part of voltage-gated potassium channel complex. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Orthologous to human SLC5A3 (solute carrier family 5 member 3). [provided by Alliance of Genome Resources, Nov 2024]

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.
