Recombinant Human AFF4 Protein, N-His

Introduction

Recombinant Human AFF4 Protein, also known as AF4/FMR2 family member 4, is a protein that plays a crucial role in transcriptional regulation and chromatin remodeling. It is encoded by the AFF4 gene located on chromosome 5 in humans. This protein has been extensively studied due to its involvement in various cellular processes and its potential as a therapeutic target. In this article, we will delve into the structure, activity, and applications of Recombinant Human AFF4 Protein.

Structure of Recombinant Human AFF4 Protein

Recombinant Human AFF4 Protein is a 170 kDa protein composed of 1532 amino acids. It belongs to the AF4/FMR2 family of proteins and contains conserved domains such as the AF4/FMR2 family conserved region (AFCR) and the serine-rich domain (SRD). The AFCR domain is essential for protein-protein interactions, while the SRD is involved in transcriptional activation. The protein also contains multiple phosphorylation sites, indicating its regulation through post-translational modifications.

Activity of Recombinant Human AFF4 Protein

Recombinant Human AFF4 Protein is a key component of the super elongation complex (SEC), which is responsible for regulating transcription elongation. It interacts with other proteins such as ELL, ELL2, and P-TEFb to form the SEC, which is recruited to the promoter regions of actively transcribed genes. This complex then facilitates the release of paused RNA polymerase II, enabling efficient transcription elongation.

Apart from its role in transcriptional regulation, Recombinant Human AFF4 Protein has also been shown to play a crucial role in chromatin remodeling. It interacts with the histone acetyltransferase p300 and the chromatin remodeling factor BRD4 to promote histone acetylation and chromatin decompaction. This activity is important for proper gene expression and cellular differentiation.

Applications of Recombinant Human AFF4 Protein

The unique structure and activity of Recombinant Human AFF4 Protein make it a valuable tool for various research applications. One of its primary uses is in studying transcriptional regulation and chromatin remodeling. Recombinant Human AFF4 Protein can be used in in vitro assays to characterize its interactions with other proteins and its role in transcriptional regulation.

Furthermore, the dysregulation of Recombinant Human AFF4 Protein has been linked to various diseases, including cancer and neurodevelopmental disorders. Thus, it has the potential to be a therapeutic target for these conditions. Recombinant Human AFF4 Protein can also be used in drug discovery and development to screen for compounds that can modulate its activity and potentially treat these diseases.

In addition, Recombinant Human AFF4 Protein has been shown to be a potential biomarker for certain cancers, such as acute lymphoblastic leukemia and breast cancer. Its expression levels in patient samples can provide valuable diagnostic and prognostic information, making it a promising biomarker for these diseases.

Conclusion

In summary, Recombinant Human AFF4 Protein is a multifunctional protein involved in transcriptional regulation and chromatin remodeling. Its unique structure and activity make it a valuable tool for studying these processes and its potential as a therapeutic target. With ongoing research, the full extent of its role in cellular processes and its potential applications will continue to be uncovered.
