Predicted to enable transmembrane transporter binding activity. Predicted to be involved in endoplasmic reticulum to Golgi vesicle-mediated transport; regulation of transcription, DNA-templated; and skeletal system development. Part of TRAPP complex. Is expressed in several structures, including eye; genitourinary system; gut; hemolymphoid system; and nervous system. Human ortholog(s) of this gene implicated in X-linked spondyloepiphyseal dysplasia tarda. Orthologous to human TRAPPC2 (trafficking protein particle complex subunit 2).
