TON1 Recruiting Motif 1 (TRM1, At3g02170) is a microtuBule-associated protein that localizes to cortical microtuBules and Binds microtuBules in vitro. It has Been shown that TRM1 interacts in vivo with TON1 (TON1A, AT3G55000; TON1B, AT3G55005) and required for Recruitment of TON1 to cortical microtuBules via its C-terminal TON1 interaction motif. TRM1 is also called as LONGIFOLIA2 (LNG2) . The homolog TRM2 (At5g15580) may has similar function.
