CC   -!- FUNCTION: Regulates flowering time via a photoperiod-dependent pathway.
CC       Suppressor of flowering that upregulates HD1 and down-regulates EHD1 in
CC       long days (LD), thus leading to the down-regulation of HD3A and RFT1.
CC       Triggers OSK4-mediated HD1 phosphorylation.
CC       {ECO:0000250|UniProtKB:Q6K678}.
CC   -!- SUBUNIT: Interacts with OSK3 and OSK4. {ECO:0000250|UniProtKB:Q6K678}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q6K678}.
CC   -!- TISSUE SPECIFICITY: Mostly expressed in leaves, seedlings and floral
CC       organs, and, to a lower extent, in panicle, roots, nodes, internodes,
CC       leaf joint and sheath. {ECO:0000250|UniProtKB:Q6K678}.
