Disease

[ENL_HUMAN] A chromosomal aberration involving MLLT1 is associated with acute leukemias. Translocation t(11;19)(q23;p13.3) with KMT2A/MLL1. The result is a rogue activator protein.

Function

[ENL_HUMAN] Component of the super elongation complex (SEC), a complex required to increase the catalytic rate of RNA polymerase II transcription by suppressing transient pausing by the polymerase at multiple sites along the DNA.^[1] ^[2]

Publication Abstract from PubMed

YEATS-domain-containing MLLT1 is an acetyl/acyl-lysine reader domain, which is structurally distinct from well-studied bromodomains and has been strongly associated in development of cancer. Here, we characterized piperazine-urea derivatives as an acetyl/acyl-lysine mimetic moiety for MLLT1. Crystal structures revealed distinct interaction mechanisms of this chemotype compared to the recently described benzimidazole-amide based inhibitors, exploiting different binding pockets within the protein. Thus, the piperazine-urea scaffold offers an alternative strategy for targeting the YEATS domain family.
