Protein
U3 small nucleolar RNA-associated protein 8
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Involved in nucleolar processing of pre-18S ribosomal RNA. Also has a role in nuclear tRNA export. It acts between the steps of tRNA maturation/aminoacylation and its subsequent translocation out of the nucleus. Required for optimal pre-ribosomal RNA transcription by RNA polymerase I together with a subset of U3 proteins required for transcription (t-UTPs).
