  • Function

    Required for centrosome assembly and function. Essential for the correct localization of several centrosomal proteins including CEP250, CETN3, PCNT and NEK2. Required to anchor microtubules to the centrosome. Involved in the biogenesis of cilia.
  • Tissue specificity

    Expressed in blood, bone marrow, breast, lymph node, ovary and thyroid.
  • Involvement in disease

    Defects in PCM1 are a cause of thyroid papillary carcinoma (TPC) [MIM:188550]. TPC is a common tumor of the thyroid that typically arises as an irregular, solid or cystic mass from otherwise normal thyroid tissue. Papillary carcinomas are malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. Note=A chromosomal aberration involving PCM1 is found in thyroid papillary carcinomas. Translocation t(8;10)(p21.3;q11.2) with RET links the protein kinase domain of RET to the major portion of PCM1.
    Note=A chromosomal aberration involving PCM1 is found in a variety of hematological malignancies including atypical chronic myeloid leukemia (atypical CML) and T-cell lymphoma. Translocation t(8;9)(p22;p24) with JAK2 links the protein kinase domain of JAK2 to the major portion of PCM1.
  • Sequence similarities

    Belongs to the PCM1 family.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Cytoplasm > cytoskeleton. Cytoplasm > cytoskeleton > centrosome. Cytoplasmic granule. Localizes to cytoplasmic granules which are enriched around the centrosome. This centrosomal enrichment requires microtubules and dynein. The majority of the protein dissociates from the centrosome during metaphase and subsequently localizes to the cleavage site in telophase.

  • All lanes : Anti-PCM1 antibody (ab72443) at 0.04 µg/ml

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg
    Lane 4 : 293T cell lysate at 50 µg
    Lane 5 : Mouse NIH3T3 cell lysate at 50 µg

    Observed band size: 270 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 60 kDa. We are unsure as to the identity of these extra bands.

    Detection: Chemiluminescence with exposure times of 30 seconds
  • Immunoprecipitation of PCM1 from 1mg HeLa whole cell lysate by 3 ug ab72443 followed by WB (20% of IP loaded):
    Lane 1: PCM1 precipitate

    Lane 2: Control IgG

    For blotting immunoprecipitated PCM1, ab72443 was used at 1 ug/ml.

    Detection: Chemiluminescence with an exposure time of 10 seconds.
