8.A.91.1.7
Syntaxin-121 of 346 aas and 1 C-terminal TMS. It is a vesicle trafficking protein that functions in the secretory pathway. It is a plasma membrane (PM)-resident syntaxin-like Q-SNARE, that interacts with QUIRKY (QKY; TC# 9.A.57.1.7), a member of the family of multiple C2 domain and transmembrane region proteins (MCTPs), to mediate FLOWERING LOCUS T transport (Liu et al. 2019).
