Circadian clock overview

Protein function

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

Phenotype

Single mutant:
toc1 single mutant is early flowering under SD conditions only. (Conflicting results under LD conditions.) [Somers et al., 1998][Strayer et al., 2000]

Function:
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. [Data from UniProt]
