Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables GTPase binding activity and guanyl-nucleotide exchange factor activity. Predicted to be involved in COPII vesicle coating; positive regulation of transcription by RNA polymerase II; and regulation of COPII vesicle coating. Predicted to act upstream of or within regulation of DNA-templated transcription. Predicted to be located in nucleus. Predicted to be active in endoplasmic reticulum exit site and endoplasmic reticulum membrane. Is expressed in several structures, including central nervous system; embryo mesenchyme; jaw; metanephros; and surface ectoderm. Orthologous to human PREB (prolactin regulatory element binding).
