Appears in the following schemes

FLC regulation through protein complexes

Protein function

Encodes a DNA-binding protein. Recruits the FRI-C complex to the FLC promoter.

Phenotype

Remarks:
suf4 mutation has only very little or no effect on the flowering time of the Col-0 background [Ding et al., 2013][Kim et al., 2006][Kim et al., 2006]

Single mutant:
suf4 mutation supresses the late-flowering phenotype of non-vernalized Col FRI plants. [Kim et al., 2006][Kim et al., 2006]

Remarks:
SUF4 overexpressor requires a functional FRI allele to delay flowering. [Kim et al., 2006]

Function:
Sequence-specific DNA binding factor that recognizes the 5 -CCAAATTTTAAGTTT-3 sequence. Recruites the FRI-C complex to the FLC promoter. Required for FRI-mediated FLC activation, but has no effect on the expression of MAF1, MAF2, MAF3, MAF5, UFC and CO. Dispensable for the reactivation of FLC in early embryogenesis, but required to maintain high levels of FLC expression in later embryonic and vegetative development. [Data from UniProt]
