    SUBCELLULAR LOCALIZATION     intracellular
  • cytoplasmically localized in spermatogonia, and its expression becomes silenced at meiotic stages due to sex-chromosome inactivation
  • basic FUNCTION
  • acting as a TATA box binding protein-associated factor
  • may have an important function in spermatogenesis
  • is required for activating adipocyte-specific genes via a dual mechanism wherein it interacts with PPARG at enhancers and TBP/Pol II at core promoters (pMID: 23326641)
  • plays an integral role in adipocyte gene expression by targeting enhancers as a cofactor for PPARG and promoters as a component of the core transcriptional machinery (pMID: 23326641)
  • TAF7L and TERF2 may actually work together in regulating spermatogenesis
  • CELLULAR PROCESS nucleotide, transcription, regulation
    a component
    small molecule
  • associates with the adipocyte-specific transcription factor PPARG during adipogenesis
  • TAF7L directly binds to gene promoters and that this binding is required for the expression of spermatogenic and metabolic genes in testis
  • interaction between a "nonprototypic" core promoter recognition factor (TERF2) and an orphan TAF subunit (TAF7L) in mammalian testis-specific gene transcription
  • cell & other
