This domain is found at the C-terminal end of of U3 small nucleolar RNA-associated protein 8 from Saccharomyces cerevisiae (Utp8) and similar proteins from fungi. Utp8 is an essential component of the nuclear tRNA export machinery in S.cerevisiae. It is a tRNA binding protein that act at a step between tRNA maturation /aminoacylation, and translocation of the tRNA across the nuclear pore complex [1]. This domain shows an all-alpha structure.
Utp13 is a component of the five protein Pwp2 complex that forms part of a stable particle subunit independent of the U3 small nucleolar ribonucleoprotein that is essential for the initial assembly steps of the 90S pre-ribosome [1]. Pwp2 is capable o ...
Utp13 is a component of the five protein Pwp2 complex that forms part of a stable particle subunit independent of the U3 small nucleolar ribonucleoprotein that is essential for the initial assembly steps of the 90S pre-ribosome [1]. Pwp2 is capable of interacting directly with the 35 S pre-rRNA 5' end [1].
The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast pro ...
The S4 domain is a small domain consisting of 60-65 amino acid residues that was detected in the bacterial ribosomal protein S4, eukaryotic ribosomal S9, two families of pseudouridine synthases, a novel family of predicted RNA methylases, a yeast protein containing a pseudouridine synthetase and a deaminase domain, bacterial tyrosyl-tRNA synthetases, and a number of uncharacterized, small proteins that may be involved in translation regulation [1]. The S4 domain probably mediates binding to RNA.
