Summary: Enables RNA 7-methylguanosine cap binding activity and RNA trimethylguanosine cap binding activity. Involved in several processes, including determination of adult lifespan; negative regulation of response to oxidative stress; and positive regulation of translation. Located in cytoplasmic stress granule. Is expressed in several structures, including excretory canal; germ line; nerve ring; neurons; and vulva. Human ortholog(s) of this gene implicated in autistic disorder. Orthologous to human EIF4E (eukaryotic translation initiation factor 4E) and EIF4E1B (eukaryotic translation initiation factor 4E family member 1B).
