**Definition:** Endogenous superantigens responsible for inducing strong proliferative responses in T-cells in mixed lymphocyte reactions (see LYMPHOCYTE CULTURE TEST, MIXED). They are encoded by mouse mammary tumor viruses that have integrated into the germ line as DNA proviruses (MINOR LYMPHOCYTE STIMULATORY LOCI).
