The majority of malignant cells showed moderate cytoplasmic staining. Renal cancer and most hepatocellular carcinomas along with a few gastric cancers were weakly stained or negative.
Malignant tissues showed moderate to strong cytoplasmic and membranous staining.
GENE INFORMATION
Gene name
STAM2 (HGNC Symbol)
Synonyms
Hbp
Description
Signal transducing adaptor molecule (SH3 domain and ITAM motif) 2 (HGNC Symbol)
Entrez gene summary
The protein encoded by this gene is closely related to STAM, an adaptor protein involved in the downstream signaling of cytokine receptors, both of which contain a SH3 domain and the immunoreceptor tyrosine-based activation motif (ITAM). Similar to STAM, this protein acts downstream of JAK kinases, and is phosphorylated in response to cytokine stimulation. This protein and STAM thus are thought to exhibit compensatory effects on the signaling pathway downstream of JAK kinases upon cytokine stimulation. [provided by RefSeq, Jul 2008]
