Target

  • Function

    May play a role in cell differentiation, proliferation and apoptosis (PubMed:24556617). Binds cholesterol in cholesterol-containing plasma membrane microdomains and may play a role in the organization of the apical plasma membrane in epithelial cells. During early retinal development acts as a key regulator of disk morphogenesis. Involved in regulation of MAPK and Akt signaling pathways. In neuroblastoma cells suppresses cell differentiation such as neurite outgrowth in a RET-dependent manner (PubMed:20818439).
  • Tissue specificity

    Isoform 1 is selectively expressed on CD34 hematopoietic stem and progenitor cells in adult and fetal bone marrow, fetal liver, cord blood and adult peripheral blood. Isoform 1 is not detected on other blood cells. Isoform 1 is also expressed in a number of non-lymphoid tissues including retina, pancreas, placenta, kidney, liver, lung, brain and heart. Found in saliva within small membrane particles. Isoform 2 is predominantly expressed in fetal liver, skeletal muscle, kidney, and heart as well as adult pancreas, kidney, liver, lung, and placenta. Isoform 2 is highly expressed in fetal liver, low in bone marrow, and barely detectable in peripheral blood. Isoform 2 is expressed on hematopoietic stem cells and in epidermal basal cells (at protein level). Expressed in adult retina by rod and cone photoreceptor cells (at protein level).
  • Involvement in disease

    Retinitis pigmentosa 41
    Cone-rod dystrophy 12
    Stargardt disease 4
    Retinal macular dystrophy 2
  • Sequence similarities

    Belongs to the prominin family.
  • Post-translational
    modifications

    Isoform 1 and isoform 2 are glycosylated.
    Acetylation at Lys-225, Lys-257 and Lys-264 by NAT8 and NAT8B may control PROM1 protein expression and its function in cell apoptosis.
  • Cellular localization

    Apical cell membrane. Cell projection, microvillus membrane. Cell projection, cilium, photoreceptor outer segment. Endoplasmic reticulum. Endoplasmic reticulum-Golgi intermediate compartment. Found in extracellular membrane particles in various body fluids such as cerebrospinal fluid, saliva, seminal fluid and urine.

Images

  • Immunohistochemical analysis of paraffin-embedded human mammary gland tissue labeling CD133 with ab216323 at 1/1000 dilution, followed by a Goat Anti-Rabbit IgG H&L (HRP), ready to use. Apical/endoluminal staining on ducts of human mammary gland (PMID: 18261235) is observed. Counter stained with hematoxylin.
    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a Goat Anti-Rabbit IgG H&L (HRP), ready to use.
    Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab216323).
