It acts as a repressor of transcription mediated by E2 factor (E2F) and influences transcriptional silencing. RB1 modulates mitochondrial activities and has a role in the organisation of heterochromatin. Mutations in the gene encoding this protein have been associated with childhood retinoblastoma._x000D_ Features and Benefits_x000D_ Evaluate our antibodies with complete peace of mind.
