Protein
WD-40 repeat-containing protein MSI4
Organism
Arabidopsis thaliana
Function
Core histone-binding subunit that may target chromatin assembly factors, chromatin remodeling factors and histone deacetylases to their histone substrates in a manner that is regulated by nucleosomal DNA. Component of the flowering autonomous pathway which positively regulates flowering by promoting transcriptional repression of the flowering repressor FLC. May promote histone deacetylation at the FLC locus leading to the formation of repressive chromatin structures. Also negatively regulates cold-responsive genes.
Similarity
Belongs to the WD repeat RBAP46/RBAP48/MSI1 family.
