HIT4_ARATH | developmental stage | Expressed predominately at the early stages during embryogenesis. |
HIT4_ARATH | function | Essential protein required for basal thermotolerance, especially during heat-induced chromocentre decondensation, thus regulating transcriptional gene silencing (TGS). |
HIT4_ARATH | subcellular location | Localizes to the chromocentre at 23 degrees Celsius, a condensed heterochromatin domain that harbors repetitive elements for which transcription is normally suppressed by transcriptional gene silencing (TGS) (PubMed:23408827, PubMed:25329561). Relocates from the chromocenter to the nucleolus in response to heat (30 hours at 37 degrees Celsius or 30 minutes at 44 degrees Celsius), before heat-induced decondensation of chromocenters occurs (PubMed:25329561). |
