Using fluorescent confocal microscopy it has been shown that proteins belonging to the septin family such as Septin 2, 3, 5, 7, and 9 are present in the somatic muscle of the earthworm Lumbricus terrestris. Septins 2 and 9 are associated with the lack of their specific concentrations in a cholinergic synapse, while septins 3, 5, and especially 7 levels correlate with quantitatively expressed binding in their localization to the motor end plate. It is assumed that Septins 3, 5 and, mostly, 7 can be involved in the mechanisms of modulation of quantal release of neurotransmitters.
