RPL3 (Ribosomal Protein L3) is a crucial component of the 60S ribosomal subunit, playing a central role in ribosome biogenesis and protein synthesis. As part of the ribosomal machinery, RPL3 facilitates mRNA decoding and peptidyl transferase activity during translation. Beyond its canonical role, RPL3 has been implicated in diverse cellular processes, including cell cycle regulation, apoptosis, and stress response. Its conserved structural domains enable interactions with rRNA and other ribosomal proteins, maintaining ribosomal integrity.
Recombinant RPL3 protein is engineered using molecular cloning techniques, typically expressed in prokaryotic (e.g., *E. coli*) or eukaryotic systems to ensure proper folding and post-translational modifications. This engineered version retains the functional properties of native RPL3 while offering high purity and consistency for experimental applications. Researchers utilize recombinant RPL3 to study ribosome assembly defects, translational regulation, and its extra-ribosomal functions in DNA repair and signaling pathways.
Emerging evidence links RPL3 dysregulation to human diseases. Abnormal expression levels are observed in cancers, where it may act as an oncogene or tumor suppressor depending on cellular context. In neurodegenerative disorders like Alzheimer's, altered RPL3 expression correlates with disrupted protein homeostasis. Recombinant RPL3 serves as a valuable tool for structural studies (e.g., cryo-EM analyses), inhibitor screening for targeted therapies, and antibody production for diagnostic assays. Recent studies also explore its potential as a biomarker for chemoresistance in cancer treatment. The development of recombinant variants with specific mutations further enables mechanistic studies of ribosomopathies and genetic disorders associated with RPL3 malfunction.
