Hierarchical Assembly Pathways of Spermine Induced Tubulin Conical-Spiral Architectures [PDF]
, 2020 Tubulin, an essential cytoskeletal protein, assembles into various morphologies by interacting with cellular factors. Spermine, an endogenous polyamine, promotes and stabilizes tubulin assemblies.

The polyamine spermine induces the unfolded protein response via the MAPK cascade in Arabidopsis
Frontiers in Plant Science, 2015 In Arabidopsis three basic region leucine zipper (bZIP) transcription factor genes, bZIP17, bZIP28 and bZIP60, play crucial roles in the unfolded protein response (UPR). Previously we found that bZIP60 is one of the spermine-induces genes.
