Background:  Brain-specific neurabin I (neural tissue-specific F-actin binding protein I) is highly concentrated in the synapse of developed neurons; it localizes in the growth cone lamellipodia during neuronal development. Suppression of endogenous neurabin in rat hippocampal neurons inhibits neurite formation. Neurabin I recruits active PP1 via a PP1-docking sequence; mutation of the PP1-binding motif halts filopodia and restores stress fibers in neurabin I-expressing cells. Neurabin II (Spinophilin) is ubiquitously expressed but is abundantly expressed in brain. Neurabin II localizes to neuronal dentritic spines, which are the specialized protrusions from dendritic shafts that receive most of the excitatory input in the CNS. Neurabin II may regulate dendritic spine properties as neurabin II(-) mice have increased spine density during development in vitro and exhibit altered filopodial formation in cultured cells. Neurabin may also play a role in glutamatergic transmission as Neurabin II(-) mice exhibit reduced long-term depression and resistance to kainate-induced seizures and neronal apoptosis. Neurabin II complexes with the catalytic subunit of protein phosphatase-1 (PP1) in vitro thus modulating the activity of PP1.
