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.  Despite the known involvement of Shq1 in H/ACA box snoRNP's production, the exact function of this protein in the overall rRNA processing pathway is still unknown.
