UniProt functional annotation for Q97ZF4

UniProt code: Q97ZF4.

Organism: Saccharolobus solfataricus (strain ATCC 35092 / DSM 1617 / JCM 11322 / P2) (Sulfolobus solfataricus).
Taxonomy: Archaea; Crenarchaeota; Thermoprotei; Sulfolobales; Sulfolobaceae; Saccharolobus.
 
Function: Binds double-stranded DNA tightly but without sequence specificity. It is distributed uniformly and abundantly on the chromosome, suggesting a role in chromatin architecture. However, it does not significantly compact DNA. Binds rRNA and mRNA in vivo. May play a role in maintaining the structural and functional stability of RNA, and, perhaps, ribosomes (By similarity). {ECO:0000250}.
 
Subunit: Homotetramer. {ECO:0000250}.
Subcellular location: Cytoplasm {ECO:0000250}. Chromosome {ECO:0000250}.
Ptm: Acetylated. Deacetylation by the SIR2-homolog deacetylase may regulate its activity (By similarity). {ECO:0000250}.
Similarity: Belongs to the histone-like Alba family. {ECO:0000305}.
