    Summary
    Enables guanyl-nucleotide exchange factor activity. Involved in several processes, including cell surface receptor protein tyrosine kinase signaling pathway; nervous system development; and regulation of signal transduction. Located in cytosol. Is expressed in several structures, including adult head; central brain primordium; embryonic/larval midgut primordium; ganglia; and gut section. Orthologous to human VAV1 (vav guanine nucleotide exchange factor 1); VAV2 (vav guanine nucleotide exchange factor 2); and VAV3 (vav guanine nucleotide exchange factor 3).
