Protein of unknown function (DUF525); Members of this family include the bacterial protein ApaG and the C termini of some F-box proteins (pfam00646). F-box proteins contain a carboxyl-terminal domain that interacts with protein substrates, so this family may be involved in protein-protein interaction. The function of ApaG proteins is unknown, but mutations in the Salmonella typhimurium ApaG homologue corD gives a phenotype of low-level cobalt resistance and decreased magnesium efflux by effects on the CorA magnesium transport system.
