MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene catalyzes the formation of 5-oxoproline from gamma-glutamyl dipeptides, the penultimate step in glutathione catabolism, and may play a critical role in glutathione homeostasis. The encoded protein may also play a role in cell proliferation, and the expression of this gene is a potential marker for cancer. Pseudogenes of this gene are located on the long arm of chromosome 5 and the short arm of chromosomes 2 and 20. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2010]

Protein Function and Prediction |
GGCT catalyzes the formation of 5-oxoproline (pyroglutamic acid) from gamma-glutamyl dipeptides (1). Oakley et al. proposed that GGCT functions in glutathione homeostasis (1). In a cell-free system, GGCT induced the release of cytochrome c from mitochondria and functions in geranylgeraniol-induced apoptosis of human leukemia U937 cells (2).
|
Expression/Localization |
GGCT is moderately expressed in several tissues, with highest levels observed in the bladder and salivary gland (1). In another study, high expression of Ggct was observed in the kidney and liver (3). In situ hybridization detected Ggct mRNA in the cytoplasm of liver hepatocytes and in the outer layer of the outer zone of the medulla of the kidney (3).
