Could be an iron transport multicopper oxidase, which is required for Fe(2+) high affinity uptake. May be required to oxidize Fe(2+) and release it from the transporter. Essential component of copper-dependent iron transport (By similarity). Involved in meiotic prophase and synaptonemal complex (SC) assembly. Binds 4 Cu cations per monomer. Present with 589 molecules/cell in log phase SD medium. Belongs to the multicopper oxidase family.
