    basic FUNCTION
  • nucleosomal binding protein altering the structure of the chromatin fiber and enhancing transcription, only from chromatin templates
  • released from chromatin in the absence of transcription
  • acting as a molecular switch regulating homeodomain transcriptional activity
  • may be required in tissues or cells undergoing proliferation and differentiation during organogenesis
  • major regulator of homeodomain transcription factor activity modulated by WNT/CTNNB signaling
  • potently repress ATP-dependent chromatin remodeling by four different molecular motor proteins (Rattner 2009)
  • act in opposition to ATP-dependent chromatin remodeling factors to restrict nucleosome mobility (Rattner 2009)
  • nuclear proteins that bind to nucleosomes and alter the structure of chromatin (Subramanian 2009)
  • facilitates the ability of the DNA repair proteins to access and repair UV-induced DNA lesions in chromatin (Subramanian 2009)
  • HMGN1, 2, and 3, promote astrocyte differentiation of neural precursor cells (NPCs) during brain development
  • HMGN1, HMGN2, HMGN3 are novel chromatin regulatory factors that control astrocyte fate decision/differentiation in parallel with or downstream of the JAK-STAT pathway
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • PITX2/HMG-17 regulatory complex acting independently of promoter targets and is a general mechanism for the control of homeodomain transcriptional activity
  • component of the global genome repair subpathway of the nucleotide excision repair pathway (Subramanian 2009)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • SENP1 can deSUMOylate SUMOylated HMGN2, and PIAS1 is the E3 ligase responsible for SUMOylation of HMGN2
