The HBP1 (Phospho-Ser402) antibody is a specialized tool used to detect the phosphorylation status of HMG-box transcription factor 1 (HBP1) at serine residue 402. HBP1 is a transcriptional repressor involved in regulating cell cycle progression, differentiation, and senescence. It binds to specific DNA sequences to inhibit the expression of target genes, such as p16INK4a and p21. which are critical for cell cycle arrest. Phosphorylation at Ser402 is a post-translational modification that modulates HBP1's stability, subcellular localization, or transcriptional activity, though its exact functional implications remain under investigation. This modification may influence interactions with signaling pathways like Wnt/β-catenin or Ras-MAPK, which are often dysregulated in cancers.
The Phospho-Ser402 antibody enables researchers to study HBP1's role in cellular responses to DNA damage, oxidative stress, or oncogenic signals. It is commonly used in techniques like Western blotting, immunofluorescence, or immunoprecipitation to assess phosphorylation dynamics in cell lines or tissues. Studies suggest that HBP1 phosphorylation may correlate with tumor suppression or progression in contexts such as glioblastoma, leukemia, or colorectal cancer. By detecting Ser402 phosphorylation, this antibody helps elucidate how HBP1 integrates signaling cues to regulate cell fate decisions, offering insights into potential therapeutic targets for cancers or degenerative diseases linked to cell cycle dysregulation. Proper validation with phosphorylation-specific controls (e.g., phosphatase treatment) is essential to ensure antibody specificity.
