nuclear receptor coactivator 1 (1441 aa)

nuclear receptor subfamily 5, group A, member 1; Transcriptional activator. Seems to be essential for sexual differentiation and formation of the primary steroidogenic tissues. Binds to the Ad4 site found in the promoter region of steroidogenic P450 genes such as CYP11A, CYP11B and CYP21B. Also regulates the AMH/Muellerian inhibiting substance gene as well as the AHCH and STAR genes. 5’-YCAAGGYC-3’ and 5’-RRAGGTCA-3’ are the consensus sequences for the recognition by NR5A1. The SFPQ-NONO- NR5A1 complex binds to the CYP17 promoter and regulates basal and cAMP-dependent transcriptional a [...] (461 aa)

nuclear receptor coactivator 2; Transcriptional coactivator for steroid receptors and nuclear receptors. Coactivator of the steroid binding domain (AF- 2) but not of the modulating N-terminal domain (AF-1). Required with NCOA1 to control energy balance between white and brown adipose tissues (1464 aa)

5’-3’ exoribonuclease 1; Major 5’-3’ exoribonuclease involved in mRNA decay. Required for the 5’-3’-processing of the G4 tetraplex-containing DNA and RNA substrates. The kinetic of hydrolysis is faster for G4 RNA tetraplex than for G4 DNA tetraplex and monomeric RNA tetraplex. Binds to RNA and DNA (By similarity). Plays a role in replication-dependent histone mRNA degradation. May act as a tumor suppressor protein in osteogenic sarcoma (OGS) (1706 aa)

RAN binding protein 2; E3 SUMO-protein ligase which facilitates SUMO1 and SUMO2 conjugation by UBE2I. Involved in transport factor (Ran-GTP, karyopherin)-mediated protein import via the F-G repeat-containing domain which acts as a docking site for substrates. Could also have isomerase or chaperone activity and may bind RNA or DNA. Component of the nuclear export pathway. Specific docking site for the nuclear export factor exportin-1. Sumoylates PML at ’Lys-490’ which is essential for the proper assembly of PML-NB (3224 aa)

DEAD (Asp-Glu-Ala-Asp) box polypeptide 20; The SMN complex plays an essential role in spliceosomal snRNP assembly in the cytoplasm and is required for pre-mRNA splicing in the nucleus. It may also play a role in the metabolism of snoRNPs (824 aa)

lysine (K)-specific demethylase 2A; Histone demethylase that specifically demethylates ’Lys- 36’ of histone H3, thereby playing a central role in histone code. Preferentially demethylates dimethylated H3 ’Lys-36’ residue while it has weak or no activity for mono- and tri-methylated H3 ’Lys- 36’. May also recognize and bind to some phosphorylated proteins and promote their ubiquitination and degradation. Required to maintain the heterochromatic state. Associates with centromeres and represses transcription of small non-coding RNAs that are encoded by the clusters of satellite repeats at [...] (1162 aa)

F-box and leucine-rich repeat protein 19; Substrate-recognition component of the SCF (SKP1-CUL1-F- box protein)-type E3 ubiquitin ligase complex (By similarity) (694 aa)
