Summary: Enables mRNA binding activity. Involved in maturation of 5.8S rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) and maturation of LSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Located in nucleolus. Orthologous to human URB1 (URB1 ribosome biogenesis homolog). [provided by Alliance of Genome Resources, Nov 2024]

Rbp95 binds to 25S rRNA helix H95 and cooperates with the Npa1 complex during early pre-60S particle maturation.
Title: Rbp95 binds to 25S rRNA helix H95 and cooperates with the Npa1 complex during early pre-60S particle maturation.
These results support the idea that Npa2p, Dbp6p, Npa1p, Nop8p, and Rsa3p work in concert during the early steps of 60S subunit biogenesis.
Title: Characterization of Saccharomyces cerevisiae Npa2p (Urb2p) reveals a low-molecular-mass complex containing Dbp6p, Npa1p (Urb1p), Nop8p, and Rsa3p involved in early steps of 60S ribosomal subunit biogenesis.
