Specificity / Sensitivity
GLTSCR2 Antibody recognizes endogenous levels of total GLTSCR2 protein. .
Species Reactivity:
Human
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Lys410 of human GLTSCR2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Glioma tumor suppressor candidate region gene 2 protein (GLTSCR2), also known as protein interacting with carboxyl terminus-1 (PICT-1), displays tumor suppressor activity, in part, by interacting with the C-terminal region of PTEN and preventing its degradation. Disruption of this interaction upregulates activity of the PI3K/Akt signaling axis and promotes cell transformation (1,2). Further evidence to support the tumor suppressor role of GLTSCR2 lies in the finding that GLTSCR2 is localized to the tumor suppressive region of chromosome 19q, which is subject to lesions in human brain tumors (3). Indeed, research studies have demonstrated that GLTSCR2 harbors nonsense mutations and deletions in glioblastomas, which lead to a decrease in GLTSCR2 protein expression (4). GLTSCR2 has also been shown to exert tumor suppressor activity through its involvement in the nucleolar stress response. Research studies indicate that in response to ribosomal stress, GLTSCR2 translocates from the nucleolus to the nucleoplasm where it binds and stabilizes p53 tumor suppressor, which results in inhibition of cell cycle progression (5).
