Receptor-binding cancer antigen expressed on SiSo cells

Gene

EBAG9

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

May participate in suppression of cell proliferation and induces apoptotic cell death through activation of interleukin-1-beta converting enzyme (ICE)-like proteases.3 Publications

Miscellaneous

May serve as a prognostic marker for cancers such as adenocarcinomas of the lung and breast cancers. It is present and overexpressed in many patients suffering from breast carcinomas, its level of expression correlates with tumor grade, suggesting that it may be involved in cancer immune escape. According to PubMed:12672804, it is however not directly a tumor-associated antigen, but it rather modulates surface expression of tumor-associated O-linked glycan Tn when it is overexpressed, suggesting that it contributes indirectly to the antigenicity of tumor cells.

Caution

It was initially reported to be a ligand for some putative receptor present on T-, B-, natural killer (NK) cells and various human cell lines. However, PubMed:12672804 showed that it does not bind any receptor.Curated
