    basic FUNCTION
  • being essential during the second catalytic step in the pre-mRNA splicing process
  • highly conserved splicing factor SLU7 is involved in 3' splice site selection and also regulates alternative splicing
  • pre-mRNA splicing regulator that is inhibited in hepatocarcinoma, and is a pivotal gene for hepatocellular homeostasis
  • is central regulator of hepatocyte identity and quiescence
  • splicing regulator SLU7 as a key mediator of genome stability
  • conserved and fundamental role of SLU7 in the preservation of genome integrity
  • CELLULAR PROCESS nucleotide, RNA splicing
    a component associated with the spliceosome
    RNA binding
    small molecule metal binding,
  • Zn2+
  • protein
  • during step 1 of splicing, PRPF8 interactions with SF3b proteins are replaced by SLU7, positioning this second step factor close to the active site, and that the DEAH-box helicases DHX16 and DHX38 cooperate through ordered interactions with GPKOW (PMIDl:
  • SLU7 and PRPF18, which promote exon ligation, bind together to the PRPF8 RNase H-like domain
  • SLU7 adopts an extended conformation, binds PRPF8 and CWC22, and is poised for selection of the 3'-splice site
  • PRPF8 plays a key role in positioning the 5'splice sites (SSs) and 3'SS, facilitated by SLU7 through interactions with PRPF8 and substrate RNA to advance exon ligation
  • cell & other
    Other complex transcription regulation mechanism that controls the spatial and temporal expression of SLU7, presumably allowing regulation of tissue-specific alternative splicing events
