CRYSTAL STRUCTURE OF THE ALBA1:ALBA2 HETERODIMER FROM SULFOLOBUS SOLFATARICUS

Template:ABSTRACT PUBMED 16004869

Function

[ALBA1_SULSO] Binds double-stranded DNA tightly but without sequence specificity. It is distributed uniformly and abundantly on the chromosome, suggesting a role in chromatin architecture. May be involved in DNA compaction. May bind rRNA and mRNA, playing a role in maintaining the structural and functional stability of RNA, and, perhaps, ribosomes.[HAMAP-Rule:MF_01122] [ALBA2_SULSO] 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).
