Determination Of An Interaction Between Nipped B-Like Protein And Mll, Adam Robert Marek Jan 2012

Determination Of An Interaction Between Nipped B-Like Protein And Mll, Adam Robert Marek

Master's Theses

The Mixed Lineage Leukemia (MLL) protein serves as a positive transcriptional regulator during hematopoietic and embryonic development. The MLL gene can undergo chromosomal translocations producing leukemia-causing fusions that retain the MLL amino-terminus, including the repression domain. A recent yeast two-hybrid screening used the MLL repression domain as bait and yielded nine positive clones of Nipped B-like (NIPBL).

NIPBL is a crucial member of the cohesin complex, which functions in the segregation of sister chromatids during cell division. However, recent evidence suggests the cohesin complex can also function as a transcriptional regulator.

In this study, we wanted to confirm this interaction …
