> "Without their efficient policing of neural activity, messages could either get lost due to insufficient signal, or flood important junctions, overwhelming key networks and burying important signals in a cacophony of noise.

> "They found the enzyme SRPK2 modifies RIM1 by adding molecules with phosphate groups onto specific links of its amino-acid structure, increasing or decreasing the number of neurotransmitter bubbles that are released into the synapse.

> "'Which effect occurs depends on the phosphorylated amino acid," says Johannes Alexander Müller, a neurophysiologist at University Hospital Bonn.
> 
> "What happens to the phosphorylated RIM1 proteins after they've done their job isn't clear, leaving room for a range of other enzymes to be at work, further fine-tuning the process.

> "As with any biological function, it can be just as handy knowing what happens when it doesn't all go according to plan. There are already genetic hints that RIM1 could be involved in conditions such as autism and schizophrenia.
