Proteolysis of MLL family proteins is essential for Tappase1-orchestrated cell cycle progression
Article Abstract:
Taspase1 was identified as the threonine endopeptidase that cleaves mixed-lineage leukemia (MLL) for proper Hox gene expression in vitro. With the aim of investigating its function in vivo, Taspase[1.sup.-/-] mice. Taspase1 deficiency results in noncleavage (nc) of MLL and MLL2 and homeotic transformations.

Bimodal degradation of MLL by [SCF.sup.Skp2] and [APC.sup.Cdc20] assures cell cycle execution: a critical regulatory circuit lost in leukemogenic MLL fusions
Article Abstract:
The bimodal degradation and the biphasic expression of MLL obtained by specialized cell cycles E3 ligases, [SCF.sup.skp2] and [APC.sup.Cdc20] are reported. Results show that a proper regulation of the MLL system is necessary in coordinating any cell cycle progression.

Taspase1: threonine aspartase required for cleavage of MLL and proper HOX gene expression
Article Abstract:
Research describes the Taspase1 protease, which cleaves the Mixed-Lineage Leukemia (MLL) gene, encoding a nuclear protein involved in sustaining HOX gene expression. Data indicate that Taspase1 acts like an endopeptidase.
