Required for extension of lifespan by sir-2.1 (PubMed:16777605). Required to modulate lifespan, in concert with hcf-1, acting redundantly with 14-3-3-like protein par-5 (PubMed:21909281). Promotes nuclear export of yap-1 (PubMed:23396260). Negatively regulates the transcriptional activity of daf-16 by sequestering it to the cytoplasm (PubMed:21531333). Interacts with daf-16 (PubMed:16777605, PubMed:21531333). Interacts with sir-2.1 (PubMed:16777605). Interacts with hcf-1 (PubMed:21909281). Belongs to the 14-3-3 family.
