Predicted to enable several functions, including FFAT motif binding activity; identical protein binding activity; and protein heterodimerization activity. Predicted to be involved in several processes, including COPII-coated vesicle budding; modulation by host of viral genome replication; and protein localization to endoplasmic reticulum. Located in endoplasmic reticulum and microtubule cytoskeleton. Orthologous to human VAPA (VAMP associated protein A). [provided by Alliance of Genome Resources, Apr 2022]
