Paraneoplastic Ma antigens (PNMA) have been identified using sera from patients with paraneoplastic neurological syndromes [].Paraneoplastic antigen Ma2 (PNMA2) is expressed by normal brain tissues and by the testicular tumours of the patients [].
The paraneoplastic Ma antigens (PNMA) have been identified using sera from patients with paraneoplastic neurological syndromes []. This family includes paraneoplastic antigen PNMA1 [], PNMA2 [], PNMA3 [], PNMA4 (also known as modulator of apoptosis 1 or MOAP-1) []and some paraneoplastic antigen-like proteins (PNMA5 and PNMA6). The family also includes modulator of apoptosis 1, which has a role in death receptor-dependent apoptosis [].
