Plays a role in interneurons differentiation . Involved in neuronal development and in neuromuscular junction formation.
Subcellular locations: Cytoplasm, Nucleus, Postsynaptic cell membrane
Upon transfection into mouse primary hippocampal neurons, localizes at excitatory, but not inhibitory, postsynaptic sites.
Expressed in fetal tissues, including in brain, intestine, lung, kidney and muscle . Isoform 1 is expressed in numerous fetal brain regions. Isoform 3 is highly expressed in numerous fetal brain regions and spinal cord .
