1.I.2.1.1
Recognized or proposed constituents or associated constituents of the plant plasmodesmata. CX32 is a transmembrane protein with 2 TMSs that contains a protein kinase domain (Maule, 2008). Formins 1 (Q9SE97) and 2 (O22824) are believed to regulate the plasmodesmata's permeability by capping, anchoring and stabilizing actin filaments that are localized to it (Diao et al. 2018). Formins are large proteins (~900 to 1,100 aas) with 2 or 3 N-terminal TMSs.
