The tetraspanins form a large family of four-transmembrane-spanning proteins that are involved in a wide range of cellular functions in mammals. In the October 15 Proceedings of the National Academy of Sciences Fradkin et al describe characterization of tetraspanin expression and functions in Drosophila (Proc Natl Acad Sci USA, 99:13663-13668, October 15, 2002).The first tetraspanin gene to be identified in flies was Latebloomer (lbm), which is expressed in motoneurons and has been implicated in
