Predicted to enable RNA binding activity and protein C-terminus binding activity. Predicted to act upstream of or within mRNA polyadenylation. Predicted to be located in cell leading edge and cytoplasmic ribonucleoprotein granule. Predicted to be part of catalytic step 2 spliceosome. Predicted to be active in cytoplasmic stress granule; cytosol; and nucleus. Is expressed in brain and testis. Orthologous to several human genes including PABPC1 (poly(A) binding protein cytoplasmic 1). [provided by Alliance of Genome Resources, Apr 2022]
