What's a GeneRIF?

The authors demonstrate that Shq1p binds the pseudourydilating enzyme Cbf5p through the C-terminal domain, in synergy with the N-terminal domain.
Title: The box H/ACA snoRNP assembly factor Shq1p is a chaperone protein homologous to Hsp90 cochaperones that binds to the Cbf5p enzyme.
the CS domain is essential for Shq1p function in H/ACA snoRNP biogenesis in vivo, possibly in an Hsp90-independent manner.
Title: Structure and functional studies of the CS domain of the essential H/ACA ribonucleoparticle assembly protein SHQ1.

Preferred Names: Hsp90 cochaperone SHQ1

NP_012162.3

Chaperone protein; required for the assembly of box H/ACA snoRNPs and thus for pre-rRNA processing; functions as an RNA mimic; forms a complex with Naf1p and interacts with H/ACA snoRNP components Nhp2p and Cbf5p; homology with known Hsp90p cochaperones; relocalizes to the cytosol in response to hypoxia
