H/ACA ribonucleoprotein complex non-core subunit NAF1 (NAF1)

RNA-binding protein required for the maturation of box H/ACA snoRNPs complex and ribosome biogenesis. During assembly of the H/ACA snoRNPs complex, it associates with the complex and disappears during maturation of the complex and is substituted by NOLA1/GAR1 to yield mature H/ACA snoRNPs complex.

Probably competes with NOLA1/GAR1 for binding with DKC1/NOLA4. .
