Several melanomas, colorectal, breast, ovarian, testicular and urothelial cancers displayed moderate cytoplasmic positivity. Few cases of colorectal, prostate and pancreatic cancers exhibited membranous staining. A rare case of mucinous cystadenocarcinoma of ovary was strongly stained. Remaining cancer tissues were weakly stained or negative.
Cancer tissues displayed weak to moderate cytoplasmic and/or nuclear positivity. Several cases of gliomas, melanomas, testicular and thyroid cancers showed strong staining.
GENE INFORMATION
Gene name
CEP170 (HGNC Symbol)
Synonyms
FAM68A, KAB, KIAA0470
Description
Centrosomal protein 170kDa (HGNC Symbol)
Entrez gene summary
The product of this gene is a component of the centrosome, a non-membraneous organelle that functions as the major microtubule-organizing center in animal cells. During interphase, the encoded protein localizes to the sub-distal appendages of mature centrioles, which are microtubule-based structures thought to help organize centrosomes. During mitosis, the protein associates with spindle microtubules near the centrosomes. The protein interacts with and is phosphorylated by polo-like kinase 1, and functions in maintaining microtubule organization and cell morphology. The human genome contains a putative transcribed pseudogene. Several alternatively spliced transcript variants of this gene have been found, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Jul 2008]
