  • Function

    Granulins have possible cytokine-like activity. They may play a role in inflammation, wound repair, and tissue remodeling.
    Granulin-4 promotes proliferation of the epithelial cell line A431 in culture while granulin-3 acts as an antagonist to granulin-4, inhibiting the growth.
  • Tissue specificity

    In myelogenous leukemic cell lines of promonocytic, promyelocytic, and proerythroid lineage, in fibroblasts, and very strongly in epithelial cell lines. Present in inflammatory cells and bone marrow. Highest levels in kidney.
  • Involvement in disease

    Defects in GRN are the cause of ubiquitin-positive frontotemporal dementia (UP-FTD) [MIM:607485]; also known as tau-negative frontotemporal dementia linked to chromosome 17. Frontotemporal dementia (FTD) is the second most common cause of dementia in people under the age of 65 years. It is an autosomal dominant neurodegenerative disease.
  • Sequence similarities

    Belongs to the granulin family.
  • Post-translational

    Granulins are disulfide bridged.
  • Cellular localization

    The molecular mass observed is consistent with what has been described in the literature (PMID: 23972823). Granulin (Progranulin, PGRN) is a 593-amino acid, 68.5-kDa cysteine-rich protein that is typically secreted in a highly glycosylated 88-kDa form.

  • Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized J774A.1 (mouse reticulum cell sarcoma monocyte macrophage cell line) cells labeling Granulin with ab187070 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining on J774A.1 cell line.

    The nuclear counter statin is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) at 1/200 dilution (red).

    Negative control: Used PBS instead of primary antibody, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution.

  • Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol-permeabilized J774A.1 (mouse reticulum cell sarcoma monocyte macrophage) cell line labeling Granulin with ab187070 at 1/1000 (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue).

    Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077), at 1/2000 dilution was used as the secondary antibody.

  • Granulin was immunoprecipitated from 0.35 mg of J774A.1 (mouse reticulum cell sarcoma monocyte macrophage cell line) whole cell lysate with ab187070 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab187070 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10,000 dilution.

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab187070 in J744A.1 whole cell lysate (-).

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 3 minutes.

  • Immunohistochemical analysis of paraffin-embedded mouse lung tissue labeling Granulin with ab187070 at 1/2000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Sporadic cytoplasmic staining in mouse lung (PMID: 23959579) is observed. Counter stained with hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).

    Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).
