Status

Functioni

Binds to membranes via its F-BAR domain and mediates membrane tubulation. Plays a role in the reorganization of the microtubule cytoskeleton via its interaction with MAPT; this decreases microtubule stability and inhibits MAPT-induced microtubule polymerization. Plays a role in cellular transport processes by recruiting DNM1, DNM2 and DNM3 to membranes. Plays a role in the reorganization of the actin cytoskeleton and in neuron morphogenesis via its interaction with COBL and WASL, and by recruiting COBL to the cell cortex. Plays a role in the regulation of neurite formation, neurite branching and the regulation of neurite length. Required for normal synaptic vesicle endocytosis; this process retrieves previously released neurotransmitters to accommodate multiple cycles of neurotransmission. Required for normal excitatory and inhibitory synaptic transmission.4 Publications

Pathology & Biotechi

Disruption phenotypei

Mice are born at the expected Mendelian rate, but display a slightly reduced body weight and reduced fertility. Mice display increased synaptic vesicle diameter and impaired compensatory synaptic vesicle endocytosis after high synapse activity. Rod photoreceptor ribbon synapses display an abnormally high number of endosome-like structures and tubular elements after light exposure. Mice display defects in excitatory and inhibitory synaptic transmission in the hippocampus, and display a tendency to seizures when confronted with novelty.1 Publication
