CTAG1A

Chr X

cancer/testis antigen 1A

Also known as: CT6.1, ESO1, LAGE-2, LAGE2A, NY-ESO-1

The protein encoded by this gene is a tumor cell antigen found in various types of cancers, which makes it a good candidate for a cancer vaccine. This gene is also highly expressed in normal ovary and testis tissues. An identical copy of this gene is found on the same chromosome. [provided by RefSeq, Dec 2015]
