This domain is involved in pre-rRNA processing [1]. It has has been shown to be required either for nucleolar retention or correct assembly of the box C/D snoRNP in Saccharomyces cerevisiae [1].


Proteins containing the PIH1 domain include kintoun, Saccharomyces cerevisiae PIH1 (protein interacting with Hsp90 1, also known as Nop17) and PIH1 domain-containing proteins.
