CC   -!- FUNCTION: Binds double-stranded DNA tightly but without sequence
CC       specificity. It is distributed uniformly and abundantly on the
CC       chromosome, suggesting a role in chromatin architecture. However, it
CC       does not significantly compact DNA. Binds rRNA and mRNA in vivo. May
CC       play a role in maintaining the structural and functional stability of
CC       RNA, and, perhaps, ribosomes. {ECO:0000255|HAMAP-Rule:MF_01122}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_01122}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01122}.
CC       Chromosome {ECO:0000255|HAMAP-Rule:MF_01122}.
CC   -!- PTM: Acetylated. Deacetylation by the SIR2-homolog deacetylase may
CC       regulate its activity. {ECO:0000255|HAMAP-Rule:MF_01122}.
CC   -!- SIMILARITY: Belongs to the histone-like Alba family.
CC       {ECO:0000255|HAMAP-Rule:MF_01122}.
