== Function ==
 +
[https://www.uniprot.org/uniprot/ALBA_PYRHO ALBA_PYRHO] 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).

The crystal structure of the Alba protein (PhoAlba) from a hyperthermophilic archaeon, Pyrococcus horikoshii OT3, was determined at a resolution of 2.8 A. PhoAlba structurally belongs to the alpha/beta proteins and is similar not only to archaeal homologues but also to RNA-binding proteins, including the C-terminal half of initiation factor 3 (IF3-C) from Bacillus stearothermophilus, an Esherichia coli protein implicated in cell division (Yhhp), and an Arabidopsis protein of unknown function. We found by gel shift assay that PhoAlba interacts with both ribonuclease P (RNase P) RNA (PhopRNA) and precursor-tRNA(Tyr) (pre-tRNA(Tyr)) in P. horikoshii. However, the addition of PhoAlba to reconstituted particles composed of PhopRNA and four or five protein subunits had little influence on either the pre-tRNA processing activity or the optimum temperature for the processing activity. These results suggest that PhoAlba contributes little to the catalytic activity of P. horikoshii RNase P.
