3.A.3.5.42 Copper (Cu+) exporting ATPase of 1254 aas and 8 TMSs, CrpA. While the A. flavus protein has not been characterized at the date of this entry, the A. fumigatus ortholog has been (Werner et al. 2023). Cellular responses used by macrophages to counteract fungal infection is the accumulation of high phagolysosomal Cu levels to destroy ingested pathogens. A. fumigatus responds by activating high expression levels of crpA, which encodes a CrpA that actively transports excess Cu+ from the cytoplasm to the extracellular environment (Werner et al. 2023). Deletion of CrpA fungal-unique amino acids 1-211, containing two N-terminal Cu-binding sites, moderately increased Cu-sensitivity but did not affect expression or localization to the ER and cell surface. Replacement of CrpA fungal-unique amino acids 542-556, consisting of an intracellular loop between the second and third TMSs resulted in ER retention of the protein and strongly increased Cu-sensitivity (Werner et al. 2023).
