**Background of YARS1 Recombinant Protein**
YARS1 (Tyrosyl-tRNA Synthetase 1) is a member of the aminoacyl-tRNA synthetase (ARS) family, enzymes essential for protein synthesis. It catalyzes the attachment of tyrosine to its cognate tRNA, ensuring the accurate translation of mRNA into proteins. Beyond its canonical role, YARS1 has been implicated in non-canonical functions, including cellular signaling, inflammation regulation, and angiogenesis.
The human YARS1 gene encodes both cytoplasmic and mitochondrial isoforms via alternative splicing, reflecting its dual localization and functional versatility. Structurally, YARS1 contains a catalytic domain conserved across ARSs, as well as unique motifs that enable interactions with other cellular components. Dysregulation of YARS1 is linked to human diseases, such as Charcot-Marie-Tooth neuropathy (CMT), where dominant mutations disrupt peripheral nerve function.
Recombinant YARS1 protein is produced using biotechnological platforms (e.g., *E. coli* or mammalian expression systems) to study its biochemical properties, structural dynamics, and disease mechanisms. Purified recombinant YARS1 serves as a tool for *in vitro* assays, drug screening, and structural studies (e.g., X-ray crystallography). Its applications extend to exploring therapeutic strategies, including targeting YARS1 in cancers where overexpression correlates with tumor progression, or modulating its extracellular signaling roles in inflammation.
Research on YARS1 also explores its potential as a biomarker or therapeutic target, particularly in autoimmune diseases and infections. Studies highlight its role in immune responses, such as acting as a chemoattractant or interacting with cytokines. The development of YARS1 inhibitors or mimetics remains an active area, bridging fundamental enzymology and clinical innovation.
In summary, YARS1 recombinant protein is a critical reagent for unraveling the multifunctional biology of tyrosyl-tRNA synthetase and advancing translational research in neurology, oncology, and immunology.
