NCBI Protein Information
tetratricopeptide repeat (TPR)-containing protein
NCBI Summary
Encodes a negative regulator of 1-aminocyclopropane-1-carboxylic acid synthase5(ACS5), which catalyze the rate-limiting step in ethylene biosynthesis. ETO1 directly interacts with ACS5 and inhibits its enzyme activity and targets it for degradation via proteasome-dependent pathway. It also interacts with CUL3 (a component of ubiquitin ligase complexes). eto1 (and eto3) mutations elevate ethylene biosynthesis by affecting the posttranscriptional regulation of ACS

UniProt Comments
Essential regulator of the ethylene pathway, which acts by regulating the stability of 1-aminocyclopropane-1-carboxylate synthase (ACS) enzymes. May act as a substrate-specific adapter that connects ACS enzymes, such as ACS5, to ubiquitin ligase complexes, leading to proteasomal degradation of ACS enzymes.
