Plasmodium falciparum domain of unknown function (CPW_WPC)
This group of sequences is defined by a domain of about 61 residues in length with six well-conserved cysteine residues and six well-conserved aromatic sites. The domain can be found in tandem repeats, and is known so far only in Plasmodium falciparum. It is named for motifs of CPxxW and (less well conserved) WPC. Its function is unknown.
