Olfactory sensory neurons (OSNs) that express the same odorant receptor project their axons to specific glomeruli in the main olfactory bulb. Protocadherin-alpha (Pcdha) proteins, diverse cadherin-related molecules that are encoded as a gene cluster, are highly concentrated in OSN axons and olfactory glomeruli. Here, we describe Pcdha mutant mice, in which(More)
Serotonergic axons from the raphe nuclei in the brainstem project to every region of the brain, where they make connections through their extensive terminal arborizations. This serotonergic innervation contributes to various normal behaviors and psychiatric disorders. The protocadherin-alpha (Pcdha) family of clustered protocadherins consists of 14(More)
Diverse protocadherins (Pcdhs), which are encoded as a large cluster (composed of alpha, beta and gamma clusters) in the genome, are localized to axons and synapses. The Pcdhs have been proposed to contribute to the generation of sophisticated neural networks and to regulate brain function. To address the molecular roles of Pcdhs in regulating individual(More)
