Cancer tissues generally displayed weak to moderate cytoplasmic staining with additional membranous positivity in many cases. Cases of thyroid, colorectal cancers and squamous cell carcinomas were strongly stained. Most lymphomas and hepatocellular carcinomas were negative.
Cancer cells generally displayed weak to moderate cytoplasmic positivity. Additional nuclear and membranous staining was observed in a few cases. Cases of colorectal, breast, ovarian and lung cancers were strongly stained. Thyroid cancers along with several cases of hepatocellular carcinomas, skin and lung cancers were negative.
Mitogen-activated protein kinase kinase kinase 13 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is a member of serine/threonine protein kinase family. This kinase contains a dual leucine-zipper motif, and has been shown to form dimers/oligomers through its leucine-zipper motif. This kinase can phosphorylate and activate MAPK8/JNK, MAP2K7/MKK7, which suggests a role in the JNK signaling pathway. [provided by RefSeq, Jul 2008]
