8.A.160.3.1
Root phototropism protein 2, RPT2, of 593 aas, possibly with 1 or 2 central TMSs. It is a KAT1 potassium channel regulator required for its accumulation (Locascio et al. 2025). This suggests a role for RPT2 in KAT1 post-translational regulation that may represent a
novel connection between light signaling and potassium channel
activity.
