Summary: Enables cupric reductase (NADH) activity and ferric-chelate reductase (NADPH) activity. Acts upstream of or within exosomal secretion; positive regulation of intrinsic apoptotic signaling pathway in response to DNA damage by p53 class mediator; and transition metal ion transport. Located in endosome membrane and plasma membrane. Is expressed in several structures, including bone; genitourinary system; liver; nervous system; and white fat. Orthologous to human STEAP3 (STEAP3 metalloreductase). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Broad expression in subcutaneous fat pad adult (RPKM 51.4), mammary gland adult (RPKM 39.1) and 19 other tissues See more

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.
