RSF1 is involved in transcription repression when recruited to DNA via the DNA binding of GAL4. It is also involved in chromatin remodeling and spacing when associated with SNF2H and transcription coactivation when associated with hepatitis B virus X protein (HBX).
The RSF1 gene is localized to the long arm of human chromosome 11 between q13.4 and q14.1. This region is amplified and rearranged in many tumors, indicating that it plays a role in tumorigenesis similar to that of other PHD-containing proteins.
