Application Abreviews Notes
ICC/IF Use at an assay dependent concentration. PubMed: 22163006
IHC-P Use a concentration of 5 µg/ml.

  • Function

    Putative GTPase which is required for clearance of acute protozoan and bacterial infections. Functions in innate immune response probably through regulation of autophagy. May regulate proinflammatory cytokine production and prevent endotoxemia upon infection. May also play a role in macrophages adhesion and motility.
  • Tissue specificity

    Widely expressed (at protein level). Expressed in several tissues including colon, small bowel and peripheral blood leukocytes.
  • Involvement in disease

    Defects in IRGM are the cause of susceptibility to inflammatory bowel disease type 19 (IBD19) [MIM:612278]. A chronic, relapsing inflammation of the gastrointestinal tract with a complex etiology. It is subdivided into Crohn disease and ulcerative colitis phenotypes. Crohn disease may affect any part of the gastrointestinal tract from the mouth to the anus, but most frequently it involves the terminal ileum and colon. Bowel inflammation is transmural and discontinuous; it may contain granulomas or be associated with intestinal or perianal fistulas. In contrast, in ulcerative colitis, the inflammation is continuous and limited to rectal and colonic mucosal layers; fistulas and granulomas are not observed. Both diseases include extraintestinal inflammation of the skin, eyes, or joints.
  • Sequence similarities

    Belongs to the interferon-inducible GTPase family.
  • Cellular localization

    Golgi apparatus membrane. Cell membrane. Cytoplasmic vesicle > phagosome membrane. Cytoplasmic vesicle > autophagosome membrane. Cell projection > phagocytic cup. Behaves like an integral membrane protein (By similarity). Recruited to the plasma membrane around forming phagocytic cups, it remains associated with maturing autophagosomes (By similarity). Preferentially associated with cis- and medial-Golgi.

Thank you for contacting Abcam.

We only know of one publication that has used ab69495, although there could be more that we are unaware of. The publication is below, also please note that we do place all of the information that we have about this antibody on the website, including any know publications:

Chang CP et al. Concanavalin A/IFN-Gamma Triggers Autophagy-Related Necrotic Hepatocyte Death through IRGM1-Mediated Lysosomal Membrane Disruption. PLoS One 6:e28323 (2011). WB, ICC/IF; Mouse. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=22163006&dopt=Abstract

We do not currently supply sample sizes of our antibodies but under our Abpromise we do guarantee them to work as stated on the datasheet. If you wish to try the antibody in an untested application or species then you could take advantage of our testing discount program. You can find more information about this from the link below:


If there is anything else I can help you with, please let me know.

Thank you for contacting us with your question. I will be happy to check with the lab and see if we can add the blocking peptide for ab69495 to the catalog. If you would like, you can also send an image of your blot and some information about your protocol and I will help figure out which band may be IRGM. It may also be possible to reduce some of the non-specific bands by making a few changes to the protocol. I look forward to hearing from you, and I will let you know once I hear back from the lab about the blocking peptide.
