As it contains cargo sorting motifs in its cytoplasmic domain, protein 3a gets localized by the cell's protein transport system to the cell membrane where it functions as an ion channel (Tan et al, 2004). This ion channel function is necessary for the protein's pro-apoptotic function (Chan et al, 2009).
