**Background of PTRHD1 Recombinant Protein**
PTRHD1 (Peptidyl-tRNA Hydrolase Domain Containing 1) is a protein encoded by the *PTRHD1* gene, located on chromosome 12p13.31 in humans. It is classified as a putative peptidyl-tRNA hydrolase (PTH), a family of enzymes critical for rescuing stalled translation processes by hydrolyzing peptidyl-tRNA molecules, thereby recycling tRNA for subsequent rounds of protein synthesis. Although its exact enzymatic mechanism remains under investigation, PTRHD1 is hypothesized to play a role in maintaining translational fidelity, particularly in neural tissues.
Interest in PTRHD1 stems from its association with neurodevelopmental disorders. Mutations or deletions in the *PTRHD1* locus have been linked to X-linked intellectual disability (XLID) and early-onset Parkinson’s disease. For instance, studies report that loss-of-function variants in *PTRHD1* correlate with intellectual disability and motor dysfunction in male patients, while female carriers may exhibit Parkinsonian symptoms due to skewed X-inactivation. This dual role highlights its importance in neuronal development and maintenance.
Recombinant PTRHD1 protein is engineered for *in vitro* studies to elucidate its structure, enzymatic activity, and interactions. Typically produced in bacterial (e.g., *E. coli*) or mammalian expression systems, it often includes affinity tags (e.g., His-tag) for purification. Researchers utilize this tool to investigate pathogenic mutations, assess hydrolase activity, and explore its interaction with translational machinery or neuroprotective pathways.
Additionally, PTRHD1 recombinant protein serves as a critical reagent in diagnostic assays and drug discovery, particularly for therapies targeting tRNA metabolism defects or neurodegenerative disorders. Its study may pave the way for novel interventions, such as enzyme replacement or gene therapy, addressing conditions tied to PTRHD1 dysfunction.
