Predicted to enable poly(A) binding activity. Predicted to contribute to poly(A)-specific ribonuclease activity. Acts upstream of or within deadenylation-dependent decapping of nuclear-transcribed mRNA; positive regulation of cytoplasmic mRNA processing body assembly; and protein targeting. Located in P-body. Orthologous to human PAN3 (poly(A) specific ribonuclease subunit PAN3). [provided by Alliance of Genome Resources, Apr 2022]
