Enables G protein-coupled receptor binding activity and receptor ligand activity. Involved in several processes, including embryonic morphogenesis; mesectoderm development; and neurogenesis. Located in cytoplasm and extracellular space. Is expressed in several structures, including epithelium; glial cell; posterior midgut primordium; sensory organ cell; and wing disc.
FB Description
folded gastrulation (fog) encodes a secreted ligand that signals via GPCRs to co-ordinate cell shape change during gastrulation; in the nervous system, it regulates motor axon guidance, glial organization and morphogenesis.
