NCBI Protein Information
histone chaperone HIRA-like protein
NCBI Summary
Encodes a nuclear localized WD-repeat containing protein involved in negative regulation of knox gene expression via epigenetic mechanism of chromatin re-organization. Interacts physically and genetically with AS1. Expressed in meristem and leaf primordia. Homozygous mutants are embryo lethal. Phenotype of cosuppressed lines is variable but show effects on leaf development similar to as1/as2.

UniProt Comments
Histone chaperone involved in maintining knox genes silencing throughout leaf development (PubMed:16243907). Involved in heterochromatic and euchromatic gene silencing, especially upon salt stress (PubMed:25600486). Involved in gene expression reprogramming during dedifferentiation probably by modifying histone H3.3 recruitment at the nucleolus (PubMed:25086063, PubMed:25600486). Contributes to maintenance of silencing of pericentromeric repeats and certain transposons (PubMed:25600486).
