Isoform 5 is expressed in non-neuronal tissues, such as monocytes/macrophages.
Cell membrane; Multi-pass membrane protein. Cell projection, axon. Mainly localizes to the axon initial segment.; [Isoform 5]: Cytoplasmic vesicle. Some vesicles are localized adjacent to melanoma invadopodia and macrophage podosomes. Does not localize to the plasma membrane.
