Summary: Enables CCR4-NOT complex binding activity and nucleic acid binding activity. Involved in several processes, including behavioral response to ethanol; head involution; and positive regulation of mRNA catabolic process. Located in neuronal ribonucleoprotein granule and nuclear envelope. Is active in muscle cell postsynaptic specialization; type Ib terminal bouton; and type Is terminal bouton. Is expressed in several structures, including adult brain cell body rind; adult head; border follicle cell; cuboidal/columnar epithelium; and germline cell. Human ortholog(s) of this gene implicated in cerebellar ataxia type 47. Orthologous to several human genes including PUM2 (pumilio RNA binding family member 2).

the catalytic activity of Pop2 deadenylase is important for Pumilio RD activity. Further, we show that the Pumilio RDs directly bind to the CNOT complex. We also report that the decapping enzyme, Dcp2, participates in repression by the N-terminus of Pumilio. These results support a model wherein Pumilio utilizes CNOT deadenylase and decapping complexes to accelerate destruction of target mRNAs.
