Predicted to enable several functions, including calcium-dependent protein binding activity; protein heterodimerization activity; and ubiquitin ligase-substrate adaptor activity. Predicted to be involved in several processes, including COPII vesicle coating; mesenchymal cell differentiation; and positive regulation of protein monoubiquitination. Predicted to be located in cytoplasm. Predicted to be part of COPII vesicle coat and Cul3-RING ubiquitin ligase complex. Orthologous to human PEF1 (penta-EF-hand domain containing 1).
