SHKBP1 and infection: This cluster contained canonical immune response genes known to be activated downstream of Imd, such as AttA, AttB, AttC, DptA, DptB, Dro, edin, Mtk, PGRP-SB1, PGRP-SD. The cluster further contained IBIN (Induced by Infection), whose exact mode of action is unknown, but whose up-regulation stimulates starch catabolism as part of an immune-induced metabolic switch, likely to make free glucose available to circulating immune cells [46].
