    Summary
    Predicted to enable zinc ion binding activity. Involved in box C/D snoRNP assembly and maturation of LSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Located in cytoplasm and nucleus. Used to study PEHO syndrome. Human ortholog(s) of this gene implicated in PEHO syndrome. Orthologous to human ZNHIT3 (zinc finger HIT-type containing 3).

      Title: Studies of mutations of assembly factor Hit1 in budding yeast suggest translation defects as the molecular basis for PEHO syndrome.
    2. The authors identified structural features associated with the requirement of Hit1p and Bcd1p zinc finger-HIT domain for cell growth and box C/D snoRNA stability under heat stress. Altogether, the data suggest an important role of zinc finger-HIT domain could be to maintain functional folding to the rest of the protein, especially under heat stress conditions.
