  • GNAT domain playing a significant role in axon targeting and synaptic communication (Simpson 2009)
  • mono polymer complex
    interspecies homolog to murine Elp3
    homolog to S.cervisiae ELP3
  • ELP3 family
  • CATEGORY enzyme
    SUBCELLULAR LOCALIZATION     intracellular
    text predominantly found in nucleus but also localized to the nucleoli and in the cytoplasm
    basic FUNCTION
  • N-acetyltransferase activity
  • may have a role for the elongator complex during transcription
  • critical regulator of axon targeting and synaptic communication (Simpson 2009)
  • involved in RNA processing (Simpson 2009)
  • promotes acetylation and counteracts HDAC6-mediated deacetylation of tubulin alpha (Creppe 2009)
  • is the acetylase component of the complex and is known to play a key role in histone acetylation
  • ELP3, and possibly the ELONGATOR complex may play a role in mitochondrial function, as well as in actin organisation and cell motility
  • having functions in HSP70-2 gene transcriptional elongation in cells (Han 2007)
  • ELP1, ELP2, ELP3, ELP4, ELP5, ELP6 plays vital roles in gene regulation
  • drives Wnt-dependent tumor initiation and regeneration in the intestine
  • implicated in translational regulation via modification of tRNA at the wobble position
  • ELP3 function is critical for translational efficiency of the genes
  • CELLULAR PROCESS nucleotide, transcription, elongation
    a component
  • one of the six subunits of the elongator complex (IKAP, ELP3, p38, p30, ELP4 and p95)
  • part of the RNA polymerase II complex (Simpson 2009)
  • subunit of the Elongator (Han 2007)
  • core Elongator complex formed by IKBKAP, ELP2, and ELP3 was rather stable, whereas ELP4, ELP5, and ELP6 might loosely contact and work together with the core Elongator to regulate cell functions
  • catalytic subunit of the Elongator complex
    small molecule nucleotide,
  • ATP
  • protein
  • interacting directly with RNAPII
  • ELP5 is required for the integrity of Elongator and directly connects ELP3 to ELP4
