NUF2

NUF2, also known as NUP98 or NUP98-HOXD, is a protein that plays a crucial role in the regulation of gene expression and DNA repair. It is a component of the nucleosome, the fundamental unit of eukaryotic chromatin, where it interacts with histone proteins to package DNA. NUF2 is essential for the proper assembly and stability of nucleosomes, which are vital for gene transcription and DNA replication.

The NUF2 protein is part of the NUF2 complex, which also includes other proteins such as NUP93, NUP98, and NUP107. This complex is involved in various cellular processes, including DNA repair, chromatin remodeling, and gene regulation. Mutations in the NUF2 gene have been linked to several genetic disorders, including Bloom syndrome and Fanconi anemia, which are characterized by genomic instability and an increased risk of cancer.

NUF2 is also a target for various therapeutic interventions, particularly in the context of cancer. Inhibitors of the NUF2 complex have shown promise in preclinical studies, as they can disrupt the assembly of nucleosomes and induce DNA damage, leading to cell death. However, further research is needed to fully understand the mechanisms of action and potential side effects of these inhibitors.

In summary, NUF2 is a multifunctional protein that plays a critical role in chromatin structure and gene regulation. Its involvement in DNA repair and its association with genetic disorders make it an important target for both basic research and therapeutic development.
