Synapse identity through specific splicing

The RNA binding protein SLM2 directs the splice isoform identity of synaptic recognition receptors.

Peptide domain links phosphate need to uptake

A conserved peptide domain allows a cell to sense how much phosphate it has and regulate uptake of more phosphate if needed.
