Is an ortholog of human EXOC4 (exocyst complex component 4). Is expressed in the embryonic cell\; the excretory canal\; and the hypodermis. Human EXOC4 exhibits Ral GTPase binding activity and protein N-terminus binding activity. Is predicted to encode a protein with the following domains: Sec8 exocyst complex component specific domain and Exocyst complex component Sec8\/EXOC4.
