The plant hormone auxin binds Tir1 (Transport Inhibitor Response 1). Tir1 is an Auxin Signaling F-box Protein (AFB) that acts as an auxin receptor. Auxin-bound Tir1 stimulates binding of SCF-Tir1 to the AUX/IAA repressor. Subsequent degradation of the repressor results in activation of AUX/IAA (i.e. auxin … See more Skp, Cullin, F-box containing complex (or SCF complex) is a multi-protein E3 ubiquitin ligase complex that catalyzes the ubiquitination of proteins destined for 26S proteasomal degradation. Along with the anaphase-promoting complex See more SCF contains a variable F-box protein and three core subunits: • F-box protein (FBP) – FBP contributes to the substrate … See more The eukaryotic cell cycle is regulated through the synthesis, degradation, binding interactions, post-translational modifications of regulatory proteins. Of these regulatory proteins, two ubiquitin ligases are crucial for progression through cell cycle … See more The first hint that led to the discovery of the SCF complex came from genetic screens of Saccharomyces cerevisiae, also known as budding yeast.

WebIt has not been easy to make sense of the pleiotropic effects of plant hormones, especially of auxins; but now, it has become possible to study these effects within the framework of what we know about signal transduction in general. Changes in local auxin concentrations, perhaps even actively maintained auxin gradients, signal to networks of transcription … WebHere we show that SCFTIR1 is required for AUX/IAA degradation. We demonstrate that SCFTIR1 interacts with AXR2/IAA7 and AXR3/IAA17, and that domain II of these proteins is necessary and sufficient for this interaction. Further, auxin stimulates binding of SCFTIR1 to the AUX/IAA proteins, and their degradation.
