    PHYSICAL PROPERTIES basic Hydrophilic
  • N-terminal domain is not needed for transcriptional activity, a LW motif, predominantly nuclear localized
  • C2C2 zinc finger domain
  • multiple consensus phosphorylation sites
    interspecies homolog to murine Tcea1
    homolog to C.elegans T24M10.1
    FAMILY transcription factor S.II family
    CATEGORY regulatory , transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • stimulating the RNA polymerase II elongation complex
  • role in transcription recovery and re-establishment of the balance between hypo- and hyper-phosphorylated RNAPolII after DNA damage repair
  • may be required to couple transcription to repair by catalyzing the reverse translocation of the arrested polymerase, allowing access of repair proteins to the site of DNA damage
  • is not limiting for the repair of transcription-blocking DNA lesions and thus the present work does not support a role for TCEA1 in transcription-coupled nucleotide excision repair
  • having a positive role in transcription of pro-oncogenic genes, its expression is elevated in various tumors
  • can influence the proliferative potential, survival and differentiation of myeloid cells
  • CELLULAR PROCESS nucleotide, transcription, elongation
    nucleotide, transcription, regulation
    a component
    small molecule metal binding,
    zinc Zn2+
  • POLR3K, RNA polymerase II in absence of transcription
  • cooperating with a transcriptional activator (EAF2)
  • bind a carrier protein(s) that accomplishes nuclear import
  • key target of RNF20 tumor suppressor activity
  • dual mode of transcriptional repression by RECQL5 that includes structural mimicry of the POLR2A-TCEA1 interaction
