The innate immune DNA sensor IFI16 is in association with H3K9 methyltransferases SUV39H1 and GLP under physiological conditions in the nucleus which facilitates the epigenetic silencing of foreign viral DNA.
Sterol kinetics and cell-based assays reveal a heretofore unknown step in cholesterol trafficking through the endolysosomal compartment, involving a direct functional interaction between NPC2 and lysosbisphosphatidic acid.
Other than its function in mechanotransduction, TMC1 is indispensable for action potential firing of auditory hair cells by mediating a leak conductance that alters tonotopically along the cochlea coil.
Diurnal variation loss of pineal allopregnanolone synthesis by light-at-night induces pituitary adenylate cyclase-activating polypeptide (PACAP) reduction and transcriptional PACAP repression in the cerebellum, with subsequent Purkinje cell death.
Expression of plant immune genes is controlled by the opposing actions of ubiquitin ligases and deubiquitinases that modify the master coactivator NPR1, thereby regulating its intrinsic transcriptional activity.
In contrast to other transcription factors, CTCF and Esrrb rapidly regain binding after replication and remain bound to their targets during mitosis, preserving local nucleosome organization throughout the cell cycle.
