As Taspase1 was shown to cleave MLL which forms complexes with E2F transcription factors to regulate Cyclins E, A, and B expression in mouse embryonic fibroblasts (MEFs), we investigated whether the cleavage of MLL by Taspase1 constitutes an essential in vivo axis for HER2/neu-induced mammary tumorigenesis.
