Probable metal transporter (By similarity). Acts downstream of PRL-1 and protects the nervous system against olfactory carbon dioxide stimulation (PubMed:31404830). Interacts with PRL-1, possibly at the plasma membrane. RNAi-mediated knockdown in the nervous system results in a held-up wing phenotype after eclosion and upon carbon dioxide stimulation. Belongs to the ACDP family.
