Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; E-box binding activity; and kinase binding activity. Predicted to be involved in several processes, including heart development; negative regulation of response to DNA damage stimulus; and regulation of transcription, DNA-templated. Predicted to act upstream of or within several processes, including animal organ development; left/right pattern formation; and negative regulation of cell differentiation involved in embryonic placenta development. Predicted to be located in cytosol; nuclear lumen; and pericentric heterochromatin. Orthologous to human SNAI1 (snail family transcriptional repressor 1).
