Tumour-associated antigens

Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

Show »« Hide

This is a set of diverse proteins that have been identified as tumour antigens. They are useful tumour markers (e.g. for diagnosis and/or prognosis) and are often potential candidates for use in cancer therapy.

Targets

Targets of relevance to immunopharmacology are highlighted in blue

folate receptor alpha Show summary »« Hide summary

MAGE family member A3 Show summary »« Hide summary More detailed page go icon to follow link

Target Id	3185
Nomenclature	MAGE family member A3
Previous and unofficial names	antigen MZ2-D \| cancer/testis antigen family 1, member 3 \| MAGE-3 antigen \| melanoma-associated antigen 3
Genes	MAGEA3 (Hs)
Ensembl ID	ENSG00000221867 (Hs)
UniProtKB AC	P43357 (Hs)
Comment	MAGEA3 is a tumour-specific antigen that is expressed in a variety of cancers, but is not detected in normal cells. Attempts to target this protein using an anti-MAGEA3 vaccine [3,6] in melanoma and non-small cell lung cancer failed in late-stage testing [7]. Most recently, it was identified as the predominant driver of progression in hepatocellular carcinoma [2].

trophoblast glycoprotein Show summary »« Hide summary More detailed page go icon to follow link

Target Id	3009
Nomenclature	trophoblast glycoprotein
Previous and unofficial names	5T4 \| 5T4-Ag \| 5T4 oncofetal antigen \| Wnt-activated inhibitory factor 1 \| WAIF1
Genes	TPBG (Hs), Tpbg (Mm), Tpbg (Rn)
Ensembl ID	ENSG00000146242 (Hs), ENSMUSG00000035274 (Mm), ENSRNOG00000010694 (Rn)
UniProtKB AC	Q13641 (Hs), Q9Z0L0 (Mm), Q5PQV5 (Rn)
Comment	Trophoblast glycoprotein (a.k.a. 5T4 oncofetal antigen) is a 72-kDa oncofetal protein whose expression on trophoblast cells mediates survival of the foetus as a semi-allograft in the mother, and is overexpressed in several cancer types where it allows the tumour to evade immune surveillance by the host.

tumor associated calcium signal transducer 2 Show summary »« Hide summary More detailed page go icon to follow link

Target Id	2837
Nomenclature	tumor associated calcium signal transducer 2
Previous and unofficial names	M1S1 \| EGP-1 \| TROP2 \| TROP-2 \| GA733-1 \| RS7 antigen [5] \| tumor-associated calcium signal transducer 2
Genes	TACSTD2 (Hs), Tacstd2 (Mm), Tacstd2 (Rn)
Ensembl ID	ENSG00000184292 (Hs), ENSMUSG00000051397 (Mm), ENSRNOG00000007740 (Rn)
UniProtKB AC	P09758 (Hs), Q8BGV3 (Mm), Q6P9Z6 (Rn)
Comment	TROP2 has been exploited as a target for cancer immunotherapy.
