CC -!- FUNCTION: BINDS TO MCB ELEMENTS (MLU I CELL CYCLE BOX) FOUND IN CC THE PROMOTER OF MOST DNA SYNTHESIS GENES. TRANSCRIPTIONAL CC ACTIVATION BY MBF HAS AN IMPORTANT ROLE IN THE TRANSITION FROM G1 CC TO S PHASE. IT MAY HAVE A DUAL ROLE IN THAT IT BEHAVES AS AN CC ACTIVATOR OF TRANSCRIPTION AT THE G1-S BOUNDARY AND AS A REPRESSOR CC DURING OTHER STAGES OF THE CELL CYCLE. CC -!- SUBUNIT: MBF CONTAINS SWI6 AND MBP1. CC -!- SUBCELLULAR LOCATION: Nuclear. CC -!- SIMILARITY: CONTAINS 2 ANK REPEATS.
