2doa is a 1 chain structure with sequence from Human. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
[ELL_HUMAN] Note=A chromosomal aberration involving ELL is found in acute leukemias. Translocation t(11;19)(q23;p13.1) with MLL/HRX. The result is a rogue activator protein.
Function
[ELL_HUMAN] Elongation factor 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. ELL also plays an early role before its assembly into in the SEC complex by stabilizing RNA polymerase II recruitment/initiation and entry into the pause site. Required to stabilize the pre-initiation complex and early elongation.[1][2][3][4][5]
