NCBI Protein Information
homeobox protein ATH1
NCBI Summary
Encodes transcription factor involved in photomorphogenesis. Regulates gibberellin biosynthesis. Activated by AGAMOUS in a cal-1, ap1-1 background. Expressed at low levels in developing stamens. Increased levels of ATH1 severely delay flowering in the C24 accession. Most remarkably, ectopically expressed ATH1 hardly had an effect on flowering time in the Col-0 and Ler accessions. ATH1 physically interacts with STM, BP and KNAT6 and enhances the shoot apical meristem defect of some of these genes suggesting a role in SAM maintenance. Nuclear localization is dependent upon interaction with STM.

UniProt Comments
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).
