Mechanism of Auxin Perception by the SCF‐TIR1 Ubiquitin Ligase

The FASEB Journal, 2008
The plant hormone auxin regulates almost every aspect of plant physiology and has fascinated biologists since Darwin's time. How plants sense and respond to auxin, however, remained mysterious until recently. In 2005, the substrate receptor subunit of the plant SCF‐TIR1 ubiquitin ligase complex was identified as the long‐sought auxin receptor.

HSP90 regulates temperature-dependent seedling growth in Arabidopsis by stabilizing the auxin co-receptor F-box protein TIR1

Nature Communications, 2016
A moderate increase in temperature promotes hypocotyl elongation in Arabidopsis. Here, Wang et al.show that elevated temperature not only increases auxin biosynthesis but also acts via the co-chaperones HSP90 and SGT1 to stabilize the TIR1 auxin receptor.

Auxin-inducible protein depletion system in fission yeast

BMC Cell Biology, 2011
Background Inducible inactivation of a protein is a powerful approach for analysis of its function within cells. Fission yeast is a useful model for studying the fundamental mechanisms such as chromosome maintenance and cell cycle.

Model of the TIR1 Pathway for Auxin-Mediated Gene Expression [PDF]

Science's STKE, 2006
Auxin mediates numerous plant responses, some of which have been shown to require transcriptional regulation. One auxin response pathway, which depends on the relief of transcriptional repression, is mediated by TIR1 (transport inhibitor response protein 1). TIR1 is an auxin receptor and also a subunit of an SCF-type ubiquitin ligase.

Structural mass spectrometry techniques for characterisation of plant and algal proteins

The Plant Journal, Volume 125, Issue 6, March 2026.
SUMMARY Structural biology can offer valuable insights into the mechanisms and functions of key proteins within plant molecular and cellular systems. However, plant proteins present several specific challenges for structural analysis, including difficulties in expression and purification, significant intrinsic disorder, and extensive post‐translational

Plant structural biology: Emerging technologies and future biological insights

The Plant Journal, Volume 125, Issue 5, March 2026.
SUMMARY Plant structural biology is entering a new era. Advances in cryo‐electron microscopy, tomography, and AI‐based prediction are making it possible to study plant macromolecular machines at near‐atomic resolution, including complexes that long resisted analysis by traditional approaches.

HSP90 Stabilizes Auxin-Responsive Phenotypes by Masking a Mutation in the Auxin Receptor TIR1 [PDF]

Plant and Cell Physiology, 2016
Heat shock protein 90 (HSP90) is a molecular chaperone that is required for the function of various substrate proteins, also known as client proteins. It is proposed that HSP90 buffers or hides phenotypic variations in animals and plants by masking mutations in some of its client proteins. However, none of the client proteins with cryptic mutations has

Adaptation of the AID system for stem cell and transgenic mouse research

Stem Cell Research, 2020
The auxin-inducible degron (AID) system is becoming a widely used method for rapid and reversible degradation of target proteins. This system has been successfully used to study gene and protein functions in eukaryotic cells and common model organisms ...
