Plays a positive role in the antiviral innate immune signaling pathway. Mechanistically, interacts with MAVS and functions as a positive regulator to promote ‘Lys-63’-linked polyubiquitination of MAVS and thus strengthens the interaction between MAVS and TRAF2 (PubMed:34880843). Also plays a role in axon and dendrite arborization during cranial nerve development. May also be important for neural crest migration and early development of other anterior structures including eye, brain and cranial cartilage (By similarity).
