Predicted to enable proline-rich region binding activity. Predicted to be involved in mRNA destabilization and posttranscriptional gene silencing. Predicted to act upstream of or within several processes, including insulin-like growth factor receptor signaling pathway; mitotic G1 DNA damage checkpoint signaling; and spinal cord motor neuron differentiation. Predicted to be located in several cellular components, including cytoplasmic stress granule; perikaryon; and proximal dendrite. Predicted to be integral component of membrane. Predicted to be part of protein-containing complex. Human ortholog(s) of this gene implicated in Parkinson's disease. Orthologous to human GIGYF2 (GRB10 interacting GYF protein 2).
