The E2F-1 (Acetyl-K117) antibody is a specialized tool used to study post-translational modifications of the E2F1 protein, a key transcription factor involved in cell cycle regulation and apoptosis. E2F1 activity is tightly controlled by interactions with retinoblastoma (RB) family proteins and post-translational modifications, including acetylation. Acetylation at lysine 117 (K117) of E2F1. mediated by acetyltransferases like p300/CBP, enhances its pro-apoptotic function by promoting dissociation from RB proteins, increasing transcriptional activity, and stabilizing the protein against degradation. This modification is dynamically regulated by histone deacetylases (HDACs) and is implicated in cellular responses to DNA damage and oncogenic stress.
The E2F-1 (Acetyl-K117) antibody specifically detects acetylated E2F1 at K117. enabling researchers to investigate its role in physiological and pathological contexts. It is widely used in techniques like Western blotting, immunoprecipitation, and chromatin immunoprecipitation (ChIP) to explore E2F1’s acetylated state in cell cycle progression, apoptosis, and cancer biology. Dysregulation of E2F1 acetylation has been linked to tumor development, as aberrant acetylation may disrupt normal cell cycle checkpoints or promote apoptosis resistance. This antibody serves as a critical reagent for studies aiming to elucidate E2F1’s post-translational regulation, its crosstalk with signaling pathways, and its potential as a therapeutic target in diseases like cancer.
