**Background of Recombinant Human DALRD3 Protein**
The human *DALRD3* gene (DALR anticodon binding domain containing 3) encodes a protein implicated in tRNA modification and translational regulation. Structurally, DALRD3 contains a conserved DALR domain, which is characteristic of enzymes involved in tRNA recognition and anticodon binding, suggesting a role in post-transcriptional RNA processing. Studies link DALRD3 to maintaining translational fidelity, potentially influencing cellular processes such as proliferation, differentiation, and stress responses. Dysregulation of DALRD3 has been observed in certain cancers and neurological disorders, though its precise mechanistic contributions remain under investigation.
Recombinant human DALRD3 protein is typically produced using heterologous expression systems (e.g., *E. coli* or mammalian cells) to enable functional and structural studies. Purified recombinant DALRD3 facilitates *in vitro* assays to dissect its enzymatic activity, RNA-binding properties, or interactions with other translational machinery components. Tags (e.g., His-tag) are often incorporated for affinity purification. Research applications include exploring its role in tRNA modification pathways, elucidating its impact on disease-associated translational dysregulation, and screening for therapeutic modulators.
As an emerging target in RNA biology, recombinant DALRD3 provides a tool to advance understanding of translation control mechanisms and their implications in health and disease.
