This domain is found in fungal proteins, including copper acquisition factor BIM1 from Cryptococcus neoformans, a cell-surface bound protein that functions in the copper-accumulation pathway shared by the CUF1-dependent copper transporter CTR1 [1,2]. BIM1 facilitates copper acquisition in the brain of mammalian hosts and acts as a copper-dependent virulence trait in fungal meningitis [1]. This domain has a lytic polysaccharide monooxygenase-like (LPMO, Pfam:PF03067) fold, which are evolutionarily related but have diverged to a different biological function.
