Is predicted to encode a protein with the following domains: SAM domain; SAM domain (Sterile alpha motif); Sterile alpha motif/pointed domain superfamily; and Epidermal growth factor receptor kinase substrate 8-like. Is an ortholog of C. elegans eps-8. In C. elegans, eps-8 is involved in several processes, including anatomical structure morphogenesis; barbed-end actin filament capping; and supramolecular fiber organization.
