GTP4 has only one known functional domain and is a member of the sugar transporter family, a subset of the major facilitator superfamily (E-value: 5.4e-36). This protein appears to be responsible for transporting sugar across the plasma membrane in response to changes in the electrochemical gradient, specifically in sugar uptake.
