FLC regulation through protein complexes

Protein function

Encodes a component of the SWR1 complex which regulates gene expression through H2A & H2A.F/Z remodelling.

Phenotype

Remarks:
pie1 single mutant has reduced FLC expression levels. [Deal et al., 2007][Noh et al., 2003]

Single mutant:
pie1 single mutant is early flowering under both SD and LD conditions. [Noh et al., 2003][March-Dü¾™†”¼az et al., 2007]

Function:
Component of the SWR1 complex which mediates the ATP-dependent exchange of histone H2A for the H2A variant H2A.F/Z leading to transcriptional regulation of selected genes (e.g. FLC) by chromatin remodeling. Probable DNA-dependent ATPase. Not involved in the repression of FLC in gametophytes, but required for the reactivation of FLC in early embryos and for the maintenance of full activation of FLC in late embryos.
