    basic FUNCTION
  • involved in the cell cycle of mammalian cells and in apoptosis
  • transport factor necessary for recycling of importin-alpha from the nucleus to the cytoplasm
  • associating with a subset of p53 target promoters, cooperating with p53 to activate transcription of these genes by altering histone modification, specifically histone H3 lysine 27
  • regulates the secretion of colorectal cells and may rgulate the metastasis of colorectal cancer
  • may be involved in the "early" and "late" metastasis of tumor cells in tumorigenesis
  • required for the expression of genes promoting invasion and metastasis
  • plays roles in the regulation of the HR activity and in chromosome stability, and is likely responsible for controlling the HR activity by directly interacting with RAD51
  • CELLULAR PROCESS cell life, proliferation/growth
    cell life, cell death/apoptosis
    nucleotide, transcription, regulation

    a component
    DNA binding to chromatin
    small molecule
  • binds strongly to NLS-free importin-alpha, and this binding is released in the cytoplasm by the combined action of RANBP1 and RANGAP1
  • is a negative regulator of CFTR-dependent fluid secretion
  • CSE1L associates with RAD51 in human cells, and negatively regulates the nuclear protein level of RAD51 under normal conditions
