nervous system

nervous system phenotype ( J:197489 )

N • in the absence of PP1, brain morphology is normal

N • 1-NA-PP1-treated mice exhibit normal synaptogenesis or formation and maintenance of functional synapse

abnormal axon extension ( J:197489 )

• ventrotemporal retina explants treated with ephrin-B2 and 1-NA-PP1 exhibit collapse of growth cones unlike control explants

• ventrotemporal retina explants treated with ephrin-B and 3-MB-PP1 exhibit collapse of growth cones unlike control explants

• after 1-NA-PP1 treatment from E13.5 to E16.5, ipsilateral retinal projections from retinal ganglion cells is reduced compared to in control mice

decreased corpus callosum size ( J:197489 )

• partial agenesis with a gap in the dorsal midline region in mice treated with 1-NA-PP1
