RPL24 Rabbit Polyclonal Antibody

RPL24, also known as ribosomal protein L24, is a key component of the eukaryotic 60S large ribosomal subunit and belongs to the ribosomal protein family. This protein is localized in the nucleus and plays a dual role in ribosome biogenesis: it not only participates as a structural protein in the folding and stabilization of ribosomal RNA (rRNA), but also interacts with the pre-rRNA processing complex in the nucleolus to promote the maturation of 28S rRNA. At the functional level, RPL24 protein is essential for maintaining ribosomal integrity and translational efficiency, and alterations in its expression levels directly affect the protein synthesis capacity of cells. Beyond its classical ribosomal function, recent studies have also revealed extraribosomal functions of RPL24 protein, such as binding to MDM2 protein and inhibiting its activity, thereby regulating cell cycle and apoptosis through the p53 signaling pathway, while also directly binding to the p53 tumor suppressor protein itself and enhancing its transcriptional activity. Mutations or aberrant expression of the RPL24 gene are closely associated with various diseases; for example, upregulation of RPL24 has been observed in multiple cancers, where its overexpression may drive tumor initiation and progression by promoting the translation of pro-oncogenic proteins, while haploinsufficiency of the RPL24 gene has been confirmed to be associated with congenital erythroid hypoplasia in certain hereditary ribosomopathies such as Diamond-Blackfan anemia. Therefore, RPL24 protein is not only a classical ribosomal component but also a signaling hub that establishes an important link between ribosomal function and tumor suppressor regulation, making it a highly attractive molecule in cancer and ribosome-related disease research.
