Domain (CC)
The transport domain consists of four transmembrane regions 3, 6, 7 and 8 and two helical hairpins HP1 and HP2. According to the one-gate elevator transport model, substrate binding and release is controlled by the helical hairpin 2 (HP2) which acts as a gate for the transport domain. HP2 gate opening enables substrate binding or release. The gate closes once one amino acid and up to three sodium ions bind to the transport domain, which subsequently triggers transmembrane elevator-like motion of the transporter across the plasma membrane.; DOMAIN: The beta-hairpin (aa 191-216) located between the helical segments of TM4 protrudes in the extracellular space and forms a docking platform for proteins of retroviral origin.
