Appears in the following schemes

FLC regulation through protein complexes
General processes & autonomous pathway

Protein function

Encodes a subunit of the FACT complex, a chromatin remodelling complex involved in the reorganization of nucleosomes.

Phenotype

Single mutant:
spt16 single mutant is early flowering under both SD and LD conditions in terms of days to flowering. However, spt16 single mutant produces more leaves than wild-type plants under SD conditions. [Lolas et al., 2010]

Remarks:
ssrp1 single mutant displays pleiotropic defects and has reduced FLC expression levels. [Lolas et al., 2010]

Function:
Component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. During transcription elongation the FACT complex acts as a histone chaperone that both destabilizes and restores nucleosomal structure. It facilitates the passage of RNA polymerase II and transcription by promoting the dissociation of one histone H2A-H2B dimer from the nucleosome, then subsequently promotes the reestablishment of the nucleosome following the passage of RNA polymerase II (Probable).
