Protein LNK4; Probable transcriptional coactivator.

Two-component response regulator-like APRR9; Transcriptional repressor of CCA1 and LHY, and positive regulator of LWD1 and LWD2 expression. Controls photoperiodic flowering response and temperature compensation. Involved in the positive and negative feedback loops of the circadian clock. Expression of several members of the ARR-like family is controlled by circadian rhythm. Regulated at the transcriptional level by a corepressor complex consisting of ELF4, ELF3, and LUX. APRR9, APRR7, and APRR5 coordinately act on the upstream region of the target genes to repress their expression from [...]

Two-component response regulator-like APRR5; Transcriptional repressor of CCA1 and LHY, thereby controlling photoperiodic flowering response. Involved in the positive and negative feedback loops of the circadian clock. With RVE8, forms a negative feedback loop of the circadian clock. Expression of several members of the ARR-like family is controlled by circadian rhythm. Proteolytic substrate of the E3 ubiquitin ligase SCF(ADO1) complex. APRR9, APRR7, and APRR5 coordinately act on the upstream region of the target genes to repress their expression from noon until midnight. The particula [...]

Transcription initiation factor IIF subunit alpha; TFIIF is a general transcription initiation factor that binds to RNA polymerase II and helps to recruit it to the initiation complex in collaboration with TFIIB. It promotes transcription elongation (By similarity); Belongs to the TFIIF alpha subunit family.

Sequence-specific DNA binding transcription factor.

Protein LNK3; Probable transcriptional coactivator.

RNA polymerase sigma factor sigE, chloroplastic/mitochondrial; Essential protein. Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites (e.g. psbA and psbD) and are then released. Essential for blue light-mediated transcription of psbD, which encodes the photosystem II reaction center protein D2. Plays a role in reproduction. Required during female gametophyte development.

Protein SCAR3; Involved in regulation of actin and microtubule organization. Part of a WAVE complex that activates the Arp2/3 complex. Regulates trichome branch positioning and expansion.

Protein LNK2; Transcriptional coactivator necessary for expression of the clock genes PRR5 and TOC1. Antagonizes REV8 function in the regulation of anthocyanin accumulation. Involved in red light input to the clock. Activates clock-controlled genes with afternoon peak. Mediates light inhibition of hypocotyl elongation. Unable to bind to DNA, but recruited to the evening element (EE)-containing region of the PRR5 and TOC1 promoters through its interaction with the DNA binding proteins REV8 and REV4.
