Species Distribution
Homologues of α-neurexin have also been found in several invertebrate species including Drosophila, Caenorhabditis elegans, honeybees and Aplysia. In Drosophila melanogaster, NRXN genes (only one α-neurexin) are critical in the assembly of glutamatergic neuromuscular junctions but are much simpler. Their functional roles in insects are likely similar to those in vertebrates.

Famous quotes containing the words species and/or distribution:
“Our species successfully raised children for tens of thousands of years before the first person wrote down the word “psychology.” The fundamental skills needed to be a parent are within us. All we’re really doing is fine-tuning a process that’s already remarkably successful.”
—Lawrence Kutner (20th century)
“My topic for Army reunions ... this summer: How to prepare for war in time of peace. Not by fortifications, by navies, or by standing armies. But by policies which will add to the happiness and the comfort of all our people and which will tend to the distribution of intelligence [and] wealth equally among all. Our strength is a contented and intelligent community.”
—Rutherford Birchard Hayes (1822–1893)
