NAIF1抗体

The NAIF1 (Nuclear Apoptosis-Inducing Factor 1) antibody is a tool used to detect the NAIF1 protein, a nuclear-localized factor implicated in apoptosis and transcriptional regulation. Initially identified for its role in promoting caspase-independent cell death, NAIF1 interacts with chromatin-modifying complexes and influences gene expression, particularly under stress conditions. Studies suggest it may act as a tumor suppressor, with reduced expression observed in cancers like gastric and hepatocellular carcinoma, correlating with poor prognosis. The antibody, typically generated in rabbits or mice using immunogenic peptide fragments, enables applications such as Western blotting, immunofluorescence, and immunohistochemistry to assess NAIF1 expression, subcellular localization, and interactions. Research highlights its involvement in DNA damage response, cell cycle arrest, and metastasis suppression through pathways like TGF-β/Smad. However, functional mechanisms remain under investigation, necessitating further exploration of its context-dependent roles in apoptosis, gene regulation, and cancer biology. Validated NAIF1 antibodies are critical for elucidating its physiological and pathological contributions.
