Several cases of ovarian, cervical, endometrial and gastric cancers showed moderate to strong cytoplasmic staining. Most other cancer tissues were weakly stained or negative.
Most of the cancer cells displayed weak to moderate cytoplasmic and/or nuclear positivity. A few lymphomas and melanomas were strongly stained. Most carcinoids and testicular cancers were negative.
GENE INFORMATION
Gene name
TRIM22 (HGNC Symbol)
Synonyms
GPSTAF50, RNF94, STAF50
Description
Tripartite motif containing 22 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. This protein localizes to the cytoplasm and its expression is induced by interferon. The protein down-regulates transcription from the HIV-1 LTR promoter region, suggesting that function of this protein may be to mediate interferon's antiviral effects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2010]
