Appears in the following schemes


Protein function

Encodes transcription factor involved in photomorphogenesis and gibberellin biosynthesis.

Phenotype

Overexpressor:
ATH1 overexpressor is late flowering under both SD and LD conditions. (Results obtained in the col-8 background.) [Proveniers et al., 2007]

Remarks:
ath1 single mutant has reduced FLC expression levels and ATH1 overexpressor has increased FLC expression levels. [Proveniers et al., 2007]

Single mutant:
ath1 single mutant is early flowering under SD conditions, but only in the Col-8 background. [Proveniers et al., 2007]

Function:
Transcription factor which may be involved in the signal transduction pathway downstream of the COP1 gene. Controls floral competency as a specific activator of FLC expression. Is responsive of the nuclear import of SHOOT MERISTEMLESS (STM). [Data from UniProt]
