The SAMD4B antibody is a research tool designed to target the SAMD4B protein, a member of the Sterile Alpha Motif (SAM) domain-containing protein family. SAMD4B, also known as SAM domain-containing protein 4B, plays roles in RNA regulation, cellular proliferation, and differentiation. It is structurally characterized by its SAM domain, which mediates protein-protein and protein-RNA interactions, influencing post-transcriptional gene expression. SAMD4B has been implicated in various biological processes, including stress granule formation, apoptosis, and epigenetic regulation, with studies linking it to cancer progression, neurological disorders, and viral infections.

Antibodies against SAMD4B are primarily used in biomedical research to investigate its expression patterns, subcellular localization, and functional mechanisms. They enable techniques like Western blotting, immunohistochemistry, and immunofluorescence, helping to elucidate SAMD4B's involvement in diseases such as breast cancer, leukemia, and glioblastoma. For instance, SAMD4B downregulation has been associated with poor prognosis in certain cancers, while its overexpression may modulate tumor suppressor pathways.

The development of high-specificity SAMD4B antibodies is critical for distinguishing SAMD4B from homologous family members (e.g., SAMD4A) and minimizing cross-reactivity. These antibodies contribute to understanding SAMD4B's role in RNA-binding complexes and its interplay with signaling pathways like mTOR and Wnt. Ongoing research aims to explore SAMD4B's therapeutic potential, making reliable antibodies essential for both basic and translational studies.
