Comments [?]

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).
Subunit Homotetramer (By similarity).
Subcellular location Cytoplasm (By similarity). Chromosome (By similarity).
Ptm Acetylated. Deacetylation by the SIR2-homolog deacetylase may regulate its activity (By similarity).
Similarity Belongs to the histone-like Alba family.
