Summary: Enables iron ion transmembrane transporter activity and monoatomic ion channel activity. Involved in several processes, including cellular response to calcium ion; cellular response to pH; and protein homotetramerization. Acts upstream of or within autophagosome maturation. Located in membrane. Is active in intracellular vesicle. Is expressed in several structures, including cochlea; genitourinary system; liver; lung; and spleen. Used to study mucolipidosis type IV. Human ortholog(s) of this gene implicated in Lisch epithelial corneal dystrophy; glycoproteinosis; and mucolipidosis type IV. Orthologous to human MCOLN1 (mucolipin TRP cation channel 1).

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.
