Protein

Two-component response regulator-like APRR1

Gene

APRR1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Controls photoperiodic flowering response. Component of the circadian clock. Expression of several members of the ARR-like family is controlled by circadian rhythm. The particular coordinated sequential expression of APRR9, APRR7, APRR5, APRR3 and APPR1 result to circadian waves that may be at the basis of the endogenous circadian clock. Positive regulator of CCA1 and LHY expression.2 Publications

Miscellaneousi

Miscellaneous

Subject of targeted degradation by the 26S proteasome. ZEITLUPE (ADO1/ZTL) is the F-box protein that associates with the SCF (for Skp/Cullin/F-box) E3 ubiquitin ligase that is responsible for marking APRR1/TOC1 for turnover. CUL1 is the functional cullin for the SCF(ZTL) complex. APRR3 binding competitively inhibits the ADO1/ZTL interaction.

Caution

Lacks the phospho-accepting Asp (here Glu-71), present in the receiver domain, which is one of the conserved features of the two-component response regulators (ARRs) family.Curated
