**Background of Recombinant Human LARP1 Protein**
La-related protein 1 (LARP1) is a conserved RNA-binding protein belonging to the LARP family, which plays critical roles in post-transcriptional gene regulation. LARP1 is particularly notable for its involvement in modulating mRNA stability, translation, and ribosome biogenesis, primarily through interactions with the mTORC1 signaling pathway. It binds to terminal oligopyrimidine (TOP) motifs in mRNAs encoding ribosomal proteins and translation factors, acting as a key regulator of cell growth and proliferation in response to metabolic and environmental cues.
Structurally, LARP1 contains a La motif (LaM) and an RNA-binding domain (RRM), which facilitate its interaction with RNA molecules. Dysregulation of LARP1 has been linked to cancers, neurodegenerative diseases, and metabolic disorders, highlighting its therapeutic potential. Recombinant human LARP1 protein, produced via expression systems like *E. coli* or mammalian cells, enables detailed mechanistic studies of its RNA-binding activity, regulatory functions, and interactions with signaling pathways.
The development of recombinant LARP1 has advanced drug discovery efforts, particularly in targeting mTOR-driven pathologies. Its application spans *in vitro* assays, structural studies, and screening for inhibitors, providing insights into its role in cellular homeostasis and disease mechanisms.
