Antigène: FUBP1 (Far Upstream Element (FUSE) Binding Protein 1 (FUBP1))

Autre désignation: FUBP1

Sujet: FUBP1 antibody detects Far upstream element binding protein 1, encoded by the FUBP1 gene on chromosome 1p31.1. FUBP1 antibody is widely used to investigate this single-stranded DNA- and RNA-binding protein that regulates transcription, mRNA stability, and translation. FUBP1 belongs to the FUBP family, which also includes FUBP2 and FUBP3, and was first identified as a regulator of c-Myc by binding the far upstream element (FUSE) located upstream of the MYC promoter. By acting as a transcriptional activator or repressor depending on cellular context, FUBP1 plays a central role in controlling cell proliferation, apoptosis, and differentiation.

Structurally, FUBP1 contains multiple KH (hnRNP K homology) domains that mediate binding to single-stranded nucleic acids. These domains allow recognition of pyrimidine-rich elements in DNA and RNA, enabling FUBP1 to regulate gene transcription and mRNA metabolism. Its nuclear localization sequences direct it to the nucleus, where it interacts with transcriptional machinery, while cytoplasmic pools of FUBP1 influence mRNA turnover and translation. This versatility positions FUBP1 as a bridge between transcriptional and post-transcriptional control.

Functionally, FUBP1 is a key regulator of c-Myc, one of the most important proto-oncogenes. It stimulates transcription by binding the FUSE region and recruiting cofactors that promote RNA polymerase II elongation. FUBP1 also regulates genes involved in apoptosis, metabolism, and cell cycle progression. In addition, FUBP1 modulates mRNA stability by interacting with AU-rich elements and influences translation of transcripts involved in development and stress responses. Researchers use FUBP1 antibody to probe these diverse functions in molecular and cancer biology.

Clinically, FUBP1 mutations and altered expression are linked to multiple cancers. Deletions of FUBP1 are common in oligodendrogliomas, where they contribute to tumor development alongside IDH1 mutations and 1p/19q codeletion. In contrast, overexpression of FUBP1 supports tumor progression in hepatocellular carcinoma, leukemia, and other malignancies by sustaining c-Myc activity. Beyond cancer, FUBP1 has been implicated in hematopoiesis, neuronal development, and metabolic regulation. Dysregulated expression is associated with developmental delay and intellectual disability syndromes. These findings underscore the importance of FUBP1 as both a biomarker and potential therapeutic target.

Experimentally, FUBP1 antibody is used in western blotting to detect the ~68 kDa protein, in immunohistochemistry to evaluate tumor samples, and in immunofluorescence to visualize its nuclear distribution. Co-immunoprecipitation with FUBP1 antibody has identified interactions with transcriptional regulators including TFIIH and p300. Studies also demonstrate interactions with splicing factors and RNA-binding proteins, linking transcriptional and post-transcriptional networks. NSJ Bioreagents supplies FUBP1 antibody to support research in oncology, gene regulation, and RNA biology.
