It plays a role in promoting tumor growth, metastasis, and tumorigenicity in several cancer types. MAGEC2 can influence the stability and function of other proteins like TRIM28, BS69, STAT3, and Rbx1. In non-neoplastic germ cells, MAGEC2 has a consistent and strong nuclear expression in immature spermatogonia and spermatocytes but weakens gradually with more mature forms like spermatids."}]}]}
