    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus
    text
  • during spermatid elongation, it localizes to the nucleus of round spermatids but exits the nucleus to the cytoplasm as cells differentiate to elongated spermatids
  • basic FUNCTION
  • coactivator putatively involved in distinct cellular differentiation programm
  • activates CREM in a phosphorylation-independent fashion
  • required for normal sperm maturation and morphology, is not essential for testicular gene expression
  • CELLULAR PROCESS cell life, differentiation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • CREM–FHL5 complex mediates the expression of many post-meiotic genes that are essential for normal spermatogenesis, thus providing a tissue-specific modulation mechanism for CREM transcription activity
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • activating CREB and CREM independently of CREBBP
  • KIF17b (interaction restricted to specific stages of spermatogenesis)
  • interact with CREM, a DNA binding transcriptional regulator necessary for spermiogenesis
  • interacts with SPAG8, which suggests that SPAG8 could be associated with FHL5 during spermatogenesis
  • cell & other
