Previous GeneCards Identifiers for AFF4 Gene
The protein encoded by this gene belongs to the AF4 family of transcription factors involved in leukemia. It is a component of the positive transcription elongation factor b (P-TEFb) complex. A chromosomal translocation involving this gene and MLL gene on chromosome 11 is found in infant acute lymphoblastic leukemia with ins(5;11)(q31;q31q23). [provided by RefSeq, Oct 2011]
GeneCards Summary for AFF4 Gene
AFF4 (AF4/FMR2 Family Member 4) is a Protein Coding gene. Diseases associated with AFF4 include Chops Syndrome and Lymphoblastic Leukemia. Among its related pathways are Formation of HIV-1 elongation complex containing HIV-1 Tat and Gene Expression. Gene Ontology (GO) annotations related to this gene include DNA binding transcription factor activity. An important paralog of this gene is AFF1.
UniProtKB/Swiss-Prot for AFF4 Gene
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.
