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.
