Key regulator of RAB11-dependent vesicular trafficking during neurite extension through polarized membrane transport. Promotes axonal elongation and contributes to the establishment of neuronal cell polarity. Involved in nerve growth factor-induced neurite formation in VAPA-dependent manner. Contributes to both the formation and stabilization of the tubular ER network. Involved in ER morphogenesis by regulating the sheet-to-tubule balance and possibly the density of tubule interconnections. Acts as an adapter protein that facilitates the interaction of KIF5A with VAPA, VAPB, SURF4, RAB11A, RAB11B and RTN3 and the ZFYVE27-KIF5A complex contributes to the transport of these proteins in neurons. Can induce formation of neurite-like membrane protrusions in non-neuronal cells in a KIF5A/B-dependent manner.
Subcellular locations: Recycling endosome membrane, Endoplasmic reticulum membrane, Cell projection, Growth cone membrane
Localizes at both dendrites and axons. Localizes to endoplasmic reticulum tubular network.
