    text
  • nucleocytoplasmic shuttling protein (Calvert 2008)
  • localized mainly to the cytoplasm and a minor population of them was suggested to be in the nucleus (Okuwaki 2010)
  • basic FUNCTION
  • may be involved in modulating chromatin formation
  • contributing to regulation of cell proliferation
  • participating in DNA replication
  • cofactor for the import of histones H2A and H2B, a chromatin assembly factor and a mitotic factor involved in regulation of bud formation (Calvert 2008)
  • cooperates with EP300 in eviction of the acetylated histones from the chromatin template (Sharma 2008)
  • promotes nucleosome assembly by eliminating nonnucleosomal histone DNA interactions (Andrews 2010)
  • histone chaperone protein suspected to be involved in the dynamical regulation of the histone H2A-H2B hetero-dimer (Okuwaki 2010)
  • with NAP1L4 mediated nucleosome formation (Okuwaki 2010)
  • possess a significantly greater nucleosome disassembly activity than NAP1L4, suggesting that NAP1L1 and NAP1L4 may play distinct roles in the regulation of histone dynamics (Okuwaki 2010)
  • is required for cohesin release and sister chromatid resolution during mitosis
  • NAP1L1 binding to cohesin is cell-cycle regulated and increases during G2/M phase

    small molecule
    protein
  • inhibiting acetylation of core histones by EP300
  • interacting with TTLL10 (Ikegami 2008)
  • balanced antagonism between NAP1L1 and PP2A controls cohesin dissociation during mitosis
  • through regulating NAP1L1, PRDM8 inhibits PI3K/AKT/mTOR signaling in Hepatocellular carcinoma (HCC)
  • cell & other
    REGULATION
    Other prenylated
    phosphorylation by CSNK2A1 appears to regulate its localization and is required for normal progression through S phase (Calvert 2008)
