STEAP3 is a metalloreductase, capable of converting iron from an insoluble ferric (Fe3+) to a soluble ferrous (Fe2+) form.[7]

STEAP3 and other STEAP protein, with the exception of STEAP1, are predicted to contain a Di-nucleotide binding domain (Rossmann Fold). This has been shown using X-ray crystallography in the cases of STEAP3 and STEAP4 (PDB: 2VNS, 2VQ3 and 2YJZ).[8][9]

Interactions

STEAP3 has been shown to interact with BNIP3L[5] and PKMYT1.[5]
