Genes affected
STEAP3 (HGNC:24592): (STEAP3 metalloreductase) This gene encodes a multipass membrane protein that functions as an iron transporter. The encoded protein can reduce both iron (Fe3+) and copper (Cu2+) cations. This protein may mediate downstream responses to p53, including promoting apoptosis. Deficiency in this gene can cause anemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]
STEAP3-AS1 (HGNC:41053): (STEAP3 antisense RNA 1)
