APOBEC3G and neoplasm: These indicate expressions of multiple A3 paralogue proteins in germinal centers of human adenoid and palatine tonsils at apparently lower levels than that of AID [20], constitutive expression of A3G, and induction of A3A protein upon IFN-α stimulation in human naive T cells [21], A3G expression in tumor-infiltrating human T cells [22] and epithelial cells of renal tubules in macaques [23].
