Circadian clock overview

Protein function

Encodes a component of the circadian clock that belongs to the PSEUDO-RESPONSE REGULATOR (PRR) family.

Phenotype

Overexpressor:
PRR3 overexpressor is late flowering under LD conditions only. [Murakami et al., 2004]

Function:
Controls photoperiodic flowering response. Component of the circadian clock. Controls the degradation of APRR1/TOC1 by the SCF(ZTL) complex. 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. [Data from UniProt]
