Genomic definition of RIM proteins: evolutionary amplification of a family of synaptic regulatory proteins☆☆Sequence data from this article have been deposited with the GenBank Data Library under Accession Nos. AF548738 and AF548739.

RIMs are synaptic proteins that are essential for normal neurotransmitter release. We now show that while invertebrates contain only a single RIM gene, vertebrates contain four: two large genes encoding RIM1alpha (0.50 Mb) or RIM2alpha, 2beta, and 2gamma (0.50-0.75 Mb) and two smaller genes encod…
