Identifier

ALBA

Protein name

RecName: Full=DNA/RNA-binding protein Alba;

Gene name

albA

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).

PTM: Acetylated. Deacetylation by the SIR2-homolog deacetylase may regulate its activity (By similarity).

SIMILARITY: Belongs to the histone-like Alba family.
