RNA-binding protein involved in deadenylation-dependent decapping of mRNAs, leading to the degradation of mRNAs. Acts as a scaffold protein that connects deadenylation and decapping machinery (By similarity). Required for the recruitment of P-body components such as cgh-1 in somatic blastomeres (PubMed:18692039). May play a role in recruiting the decapping enzyme dcap-1 to cytoplasmic puncta in the cell body of the posterior touch receptor neuron, PLM (PubMed:31983639). Localizes to germline and somatic blastomeres (at protein level). RNAi-mediated knockdown reduces the number of cgh-1-positive foci in somatic blastomeres. Belongs to the PAT1 family.
