The E3 ubiquitin- protein ligase activity of the complex is dependent on the neddylation of the cullin subunit and is inhibited by the association of the deneddylated cullin subunit with TIP120A/CAND1. The functional specificity of the E3 ubiquitin-protein ligase complex depends [...] (759 aa) |
| | Ddx49 | Probable ATP-dependent RNA helicase DDX49. (480 aa) |
| | Ddx56 | Probable ATP-dependent RNA helicase DDX56; May play a role in later stages of the processing of the pre- ribosomal particles leading to mature 60S ribosomal subunits. Has intrinsic ATPase activity (By similarity); Belongs to the DEAD box helicase family. DDX56/DBP9 subfamily. (546 aa) |
| | Utp20 | Small subunit processome component 20 homolog; Involved in 18S pre-rRNA processing. Associates with U3 snoRNA (By similarity). (2789 aa) |
| | Emg1 | Ribosomal RNA small subunit methyltransferase NEP1; S-adenosyl-L-methionine-dependent pseudouridine N(1)- methyltransferase that methylates pseudouridine at position 1248 (Psi1248) in 18S rRNA. Involved the biosynthesis of the hypermodified N1-methyl-N3-(3-amino-3-carboxypropyl) pseudouridine (m1acp3-Psi) conserved in eukaryotic 18S rRNA. Is not able to methylate uridine at this position. Has also an essential role in 40S ribosomal subunit biogenesis independent on its methyltransferase activity, facilitating the incorporation of ribosomal protein S19 during the formation of pre- ribos [...] (244 aa) |
| | Ppan | Suppressor of SWI4 1 homolog; May have a role in cell growth. (470 aa) |
| | Nob1 | RNA-binding protein NOB1; May play a role in mRNA degradation (By similarity). Endonuclease required for processing of 20S pre-rRNA precursor and biogenesis of 40S ribosomal subunits (By similarity). (403 aa) |
| | Pwp1 | Periodic tryptophan protein 1 homolog; Chromatin-associated factor that regulates transcription (By similarity). Regulates Pol I-mediated rRNA biogenesis and, probably, Pol III-mediated transcription (By similarity). Regulates the epigenetic status of rDNA (By similarity). (501 aa) |
| | Ddx18 | ATP-dependent RNA helicase DDX18; Probable RNA-dependent helicase; Belongs to the DEAD box helicase family. DDX18/HAS1 subfamily. (660 aa) |
| | Nom1 | Nucleolar MIF4G domain-containing protein 1; Plays a role in targeting PPP1CA to the nucleolus. (854 aa) |
| | Rrp15 | RRP15-like protein. (281 aa) |
| | Nsun5 | Probable 28S rRNA (cytosine-C(5))-methyltransferase; S-adenosyl-L-methionine-dependent methyltransferase that specifically methylates the C(5) position of a cytosine in 28S rRNA. Belongs to the class I-like SAM-binding methyltransferase superfamily. RsmB/NOP family. (465 aa) |
| | Ddx3x | ATP-dependent RNA helicase DDX3X; Multifunctional ATP-dependent RNA helicase. The ATPase activity can be stimulated by various ribo-and deoxynucleic acids indicative for a relaxed substrate specificity. In vitro can unwind partially double-stranded DNA with a preference for 5'-single-stranded DNA overhangs. Binds RNA G-quadruplex (rG4s) structures, including those located in the 5'-UTR of NRAS mRNA. Involved in many cellular processes, which do not necessarily require its ATPase/helicase catalytic activities. Involved in transcription regulation. Positively regulates CDKN1A/WAF1/CIP1 t [...] (662 aa) |
| | C1d | Nuclear nucleic acid-binding protein C1D; Plays a role in the recruitment of the RNA exosome complex to pre-rRNA to mediate the 3'-5' end processing of the 5.8S rRNA; this function may include MPHOSPH6. Can activate PRKDC not only in the presence of linear DNA but also in the presence of supercoiled DNA. Can induce apoptosis in a p53/TP53 dependent manner. May regulate the TRAX/TSN complex formation. Potentiates transcriptional repression by NR1D1 and THRB (By similarity); Belongs to the C1D family. (141 aa) |
