 Although many of the intermediates in this rRNA processing pathway have been identified in the last thirty years, there are still a number of proteins involved in this process whose specific function is unknown.Shq1, a protein thought to play a role in the stabilization and/or production of box H/ACA snoRNA, is still uncharacterized.It has been proposed that Shq1, along with Naf1p, is involved in the initial steps of the biogenesis of H/ACA box snoRNPs (box H/ACA snoRNAs form complexes with proteins, thereby forming snoRNPs) because of its association with certain snoRNP proteins during the snoRNP’s maturation, while showing very little association with the mature snoRNP complex.
