Lva and spectrin may form a Golgi-based scaffold that mediates interaction of Golgi bodies with microtubules and facilitates Golgi-derived membrane secretion required for the formation of furrows during cellularization (PubMed:11076973). Under starvation conditions recruited by ema to developing autophagsosomes where it may function in autophagosome growth (PubMed:22493244). Interacts with CLIP-190 and spectrin separately. Lva-alpha-spectrin and Lva-CLIP-190 complexes are found at the Golgi (PubMed:11076973). Upon autophagosome induction by starvation, also detected in small vesicle structures (PubMed:22493244).
