RBAK, ZNF769, RB-associated KRAB zinc finger protein, RB-associated KRAB repressor, Zinc finger protein 769

This gene encodes a nuclear protein which interacts with the tumor suppressor retinoblastoma 1. The two interacting proteins are thought to act as a transcriptional repressor for promoters which are activated by the E2F1 transcription factor. This protein contains a Kruppel-associated box (KRAB), which is a transcriptional repressor motif.
