new spindle pole body SIN signaling complex

A SIN signaling complex associated with the new mitotic spindle pole body during anaphase and characterized by the presence activated (GTP bound) GTPase (Spg1 in fission yeast) to activate SIN signaling.

interphase SIN signaling complex

A SIN signaling complex associated with the old mitotic spindle pole body during interphase and early M-phase and characterised by the presence active ubiquitin ligase (Dma1 in fission yeast) and GTPase activator (Spg1 in fission yeast) to inactivate SIN signaling.

establishment of septation initiation network asymmetry

The septation initiation signaling process by which the activity of the septation initiation network (SIN) is activated asymmetrically on the spindle pole bodies.

SIN/MEN signaling complex

A protein complex associated with the mitotic spindle pole body during interphase and mitosis and comprises of the proteins of the septation initiation signaling network (SIN) of fission yeast or mitotic exit network (MEN) of budding yeast, organized by two scaffold/adaptor proteins.
