Predicted to enable RNA binding activity and protein C-terminus binding activity. Involved in gene silencing by RNA; positive regulation of nuclear-transcribed mRNA catabolic process, deadenylation-dependent decay; and positive regulation of nuclear-transcribed mRNA poly(A) tail shortening. Located in cytoplasm and synapse. Is expressed in several structures, including central nervous system; early conceptus; gonad; gut; and sensory organ. Orthologous to several human genes including PABPC1 (poly(A) binding protein cytoplasmic 1). [provided by Alliance of Genome Resources, Apr 2022]
