**Background of Recombinant RPL7A Protein**
Recombinant RPL7A protein is a laboratory-engineered version of the ribosomal protein L7a, encoded by the *RPL7A* gene in humans. As a component of the 60S ribosomal subunit, RPL7A plays a critical role in ribosome assembly and protein synthesis by stabilizing rRNA structure and facilitating interactions during translation. Beyond its canonical ribosomal functions, RPL7A has been implicated in extraribosomal activities, including cell cycle regulation, apoptosis, and DNA repair, through interactions with non-ribosomal proteins and nucleic acids.
The production of recombinant RPL7A involves cloning the *RPL7A* gene into expression vectors, followed by overexpression in host systems such as *E. coli* or mammalian cell lines. Affinity tags (e.g., His-tag, FLAG) are often incorporated to enable purification via chromatography. This recombinant approach ensures high purity and consistency, making it valuable for functional studies, structural analyses (e.g., X-ray crystallography, cryo-EM), and investigations into disease mechanisms. Dysregulation of RPL7A has been linked to cancers, developmental disorders, and ribosomopathies, highlighting its biomedical relevance.
Additionally, recombinant RPL7A serves as a tool to study ribosome biogenesis defects or mutations associated with genetic disorders. Its role in mediating cellular stress responses and potential as a therapeutic target further underscore its importance in molecular and translational research.
