Predicted to enable RNA binding activity and poly(A)-specific ribonuclease activity. Predicted to be involved in nuclear-transcribed mRNA poly(A) tail shortening. Predicted to act upstream of or within blastocyst formation. Predicted to be active in endoplasmic reticulum. Human ortholog(s) of this gene implicated in spermatogenic failure. Orthologous to human PNLDC1 (PARN like ribonuclease domain containing exonuclease 1). [provided by Alliance of Genome Resources, Apr 2022]
