It has been shown that Latrophilin-1 has a trans function in the Caenorhabditis elegans nervous system, mediating the morphogenesis of sensory structures and playing a physiological role in copulation behavior. Detailed analysis revealed specific LAT-1-positive neurons and the genetic network modulated by the receptor function.
Latrophilins are highly conserved Adhesion GPCRs playing essential roles in the mammalian nervous system and are associated with severe neurological disorders. Recently, it has been shown that murine Latrophilins mediate classical G-protein signals to drive synaptogenesis. However, there is evidence that Latrophilins in the nematode Caenorhabditis elegans can also function independently of their seventransmembrane domain and C terminus (trans function). Here, we show that Latrophilin-1 acts in trans to mediate morphogenesis of sensory structures in the C. elegans nervous system. This trans function is physiologically relevant in copulation behavior. Detailed expression and RNA-Seq analyses revealed specific LAT-1-positive neurons and first insights into the genetic network that is modulated by the receptor function. We conclude that 7TM-independent functions of Latrophilins are essential for neuronal physiology, possibly complementing canonical functions via G protein-mediated signaling. (c) 2021 Elsevier Inc.
