Cell growth-regulating nucleolar protein (Lyar)

Plays a role in the maintenance of the suitable processing of 47S/45S pre-rRNA to 32S/30S pre-rRNAs and their subsequent processing to make 18S and 28S rRNAs (By similarity). Also acts at the level of transcription regulation.

Along with PRMT5, binds embryonic globin promoter (By similarity). In neuroblastoma cells, may also repress the expression of oxidative stress genes, such as CHAC1, HMOX1, SLC7A11, ULBP1 and that encoding the small nucleolar RNA SNORD41 (By similarity).
