AFF4 Information: AFF4 Protein, AFF4 Antibody and AFF4 Gene

AFF4 Gene family

AFF4 Protein

AFF4 protein function

Key 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. In the SEC complex, AFF4 acts as a central scaffold that recruits other factors through direct interactions with ELL proteins (ELL, ELL2 or ELL3) and the P-TEFb complex. In case of infection by HIV-1 virus, the SEC complex is recruited by the viral Tat protein to stimulate viral gene expression.

AFF4 protein expression

Tissue specificity

Ubiquitously expressed. Strongly expressed in heart, placenta, skeletal muscle, pancreas and to a lower extent in brain.


Expressed in fetal heart, lung, brain and to a lower extent liver.
