Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Component of an E3 ubiquitin ligase complex that plays a central role in blue light-dependent circadian cycles. Acts as a blue light photoreceptor, due to the presence of FMN, that mediates light-regulated protein degradation of critical clock components by targeting them to the proteasome complex. The SCF(ADO1) E3 ubiquitin ligase complex is involved in the regulation of circadian clock-dependent processes including the transition to flowering time, hypocotyl elongation, cotyledons and leaf movement rhythms. APRR1/TOC1 and APRR5, but not 'GIGANTEA', are proteolytic substrates of this ubiquitin ligase complex. Blue light enhances cooperative stabilization of 'GIGANTEA' and ADO1/ZTL, leading to amplification and sharpening of the expression profile of APRR1/TOC1. ADO1/ZTL interacts with ADO3, preventing the interaction of ADO3 with CDF1.PATHWAY Protein modification; protein ubiquitination.SUBUNIT Interacts with NFXL2. Interacts (via N-terminus) with GI and (via Kelch repeats) with ADO3. Component of an E3 ubiquitin ligase SCF(ADO1) complex composed of SKP1A/ASK1 (or SKP1B/ASK2), CUL1, RBX1 and ADO1. Also interacts with SKP1D/ASK4, SKP1K/ASK11, CRY1, PHYB, APRR1 and APRR5, and probably with SKP1N/ASK14 and SKP1S/ASK19.INTERACTION Nuclear after 9 hours of illumination (afternoon of long days). Cytoplasmic when plant have been subsequently grown 16 hours in light and 5 hours in dark (early morning of long days).ALTERNATIVE PRODUCTS A number of isoforms are produced. According to EST sequences.TISSUE SPECIFICITY Ubiquitously expressed with higher levels in cotyledons and leaves.DEVELOPMENTAL STAGE Mainly present during the light phase, and degraded in a proteasome-dependent manner in dark (at protein level).INDUCTION Not regulated at the transcript level, but circadian-regulation at the protein level with a peak at the end of the subjective day.PTM May be ubiquitinated. Degraded in a proteasome-dependent manner.PTM FMN binds covalently to cysteine after exposure to blue light and is reversed in the dark.DISRUPTION PHENOTYPE Accumulation of ADO3 protein during the morning period and early flowering time.MISCELLANEOUS 'Zeitlupe' means slow motion in German.MISCELLANEOUS 'Adagio' means slowly in Italian.SIMILARITY Belongs to the ADAGIO family.
