Enables protein N-terminus binding activity and small GTPase binding activity. Predicted to be involved in Golgi to plasma membrane transport; exocytosis; and regulation of entry of bacterium into host cell. Predicted to act upstream of or within positive regulation of exocytosis. Predicted to be located in plasma membrane. Predicted to be part of exocyst. Is expressed in several structures, including early conceptus and genitourinary system. Orthologous to human EXOC2 (exocyst complex component 2). [provided by Alliance of Genome Resources, Apr 2022]
