Protein: T-cell-specific guanine nucleotide triphosphate-binding protein 1 (EC 3.6.5.-) (Interferon-gamma-inducible GTPase Ifggb5) (Q62293)
Organism: Mus musculus (Mouse)
Function: Involved in innate cell-autonomous resistance to intracellular pathogens, such as Toxoplasma gondii. During avirulent type II T. gondii infection, recruited to the parasitophorous vacuole (PV) membrane, leading to PV vesiculation and rupture, and subsequent digestion of the parasite within the cytosol. Not recruited to virulent type I T. gondii PV membrane. May confer an antiviral state for vesicular stomatitis virus.
Subcellular location: Cytoplasm {ECO:0000269|PubMed:19285957}. Endoplasmic reticulum {ECO:0000269|PubMed:19285957}. Golgi apparatus {ECO:0000269|PubMed:19285957}. Note=In astrocytes stimulated with IFNG or TNF, diffuse cytoplasmic localization decreases and the protein partially relocalizes to the endoplasmic reticulum and Golgi apparatus (PubMed:19285957). Due to sequence similarity with Tgtp2, it is impossible to assign unambiguously experimental data published in the literature to Tgtp1 or Tgtp2 gene (Probable). {ECO:0000269|PubMed:19285957, ECO:0000305|PubMed:22892676}.
