  • Function

    Interacts with RB1 and EP300 and acts as a repressor of MYOD1 transactivation. Inhibits EP300 and CBP histone acetyltransferase activity. May be involved in coupling cell cycle exit to the transcriptional activation of genes required for cellular differentiation. May act as a candidate coinhibitory factor for NR0B2 that can be directly linked to transcription inhibitory mechanisms.
  • Tissue specificity

    Widely expressed. Most abundantly expressed in heart, skeletal muscle, pancreas, brain and testis. Expressed at much lower levels in placenta and peripheral blood leukocyte. Barely detectable in lung. Also weakly expressed in lung carcinoma A549 and various leukemia cell lines.
  • Developmental stage

    Expression decreased with development in ventricular tissue while remaining highly expressed in adult atrial tissue. In primary cultures of human skeletal myocytes, expression decreased during myogenic differentiation (at protein level).
  • Post-translational

    Ubiquitinated in U-2OS osteosarcoma cells and is rapidly degraded by proteasome as cells exit the cell cycle exit.
  • Cellular localization

    Nucleus. Cytoplasm. May shuttle between nucleus and cytoplasm.

  • ab78323 staining EID1 in HeLA cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% paraformaldehyde, permeabilized with Triton X-100 0.25% in PBS and blocked with 1.5% BSA for 30 minutes. Samples were incubated with primary antibody (1/100 in PBS + 1% BSA) overnight at 4°C. An Alexa Fluor®488-conjugated Goat anti-mouse IgG polyclonal (1/1000 in PBS + 1% BSA) was used as the secondary antibody incubated for 1 hour. DAPI was used to stain the nuclear DNA.
