The PIWIL4 antibody is a research tool designed to detect and study the PIWI-like protein 4 (PIWIL4), a member of the PIWI/Argonaute protein family. PIWI proteins are evolutionarily conserved RNA-binding proteins primarily implicated in germline development, stem cell maintenance, and RNA silencing pathways. PIWIL4. also known as HIWI2. plays a critical role in regulating transposon silencing through interactions with PIWI-interacting RNAs (piRNAs), safeguarding genome integrity during gametogenesis. Dysregulation of PIWIL4 has been linked to germ cell tumors, infertility, and somatic cancers, where its aberrant expression may influence tumorigenesis, metastasis, or therapy resistance.
PIWIL4 antibodies are widely used in molecular and cellular biology to investigate protein expression patterns, subcellular localization (e.g., cytoplasmic or nuclear), and functional roles in development or disease. Common applications include Western blotting, immunohistochemistry, immunofluorescence, and co-immunoprecipitation. These antibodies aid in elucidating PIWIL4's interactions with piRNA complexes, its regulatory mechanisms in epigenetic modifications, and its potential as a diagnostic biomarker or therapeutic target. Validation of antibody specificity (e.g., via knockout controls) is essential due to structural homology among PIWI family members. Ongoing research continues to explore PIWIL4's dual roles in both physiological processes and pathological contexts.
