Protein Name: AF4/FMR2 family member 4

UniprotKB/SwissProt ID: Q9UHB7 (Q9UHB7)

Gene Name: AFF4

Organism: Homo sapiens (Human)

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
