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.

Supplementary info

- Activity summary
The AFF4 protein also known as AF4/FMR2 family member 4 is a transcriptional cofactor with a molecular weight of approximately 140 kDa. It plays a role in regulating transcriptional elongation by RNA polymerase II. This protein shows expression across diverse tissues with higher levels in the brain and testis. AFF4 contains domains that enable interactions with other proteins facilitating its role in transcriptional regulation.
- Biological function summary
AFF4 functions as a component of the super elongation complex (SEC) which is essential for transcriptional elongation of specific genes. This complex ensures efficient transcription after the initiation phase. Through its association with SEC AFF4 influences the expression of genes involved in cellular differentiation and development. Its activity is particularly impactful on genes associated with oncogenesis and neural development affecting cellular growth and specialized cell formation.
- Pathways
The function of AFF4 integrates into the transcription elongation and gene regulation pathways. AFF4 interacts with proteins like ELL2 and CDK9 which are critical components of the positive transcription elongation factor b (P-TEFb) complex. Together these proteins regulate polymerase activity and gene expression fundamental in cell cycle control and response to growth signals.
- Associated diseases and disorders
AFF4 has connections to cancer and neurological disorders. Mutations or altered expressions of AFF4 relate to acute lymphoblastic leukemia where it may form fusion proteins that disrupt normal gene expression. In neurological contexts aberrant AFF4 function can contribute to disorders such as developmental delay. Through these diseases AFF4 interacts with disease-related proteins like MLL and AF9 involved in oncogenic transformations and neurological development respectively.
