**Background of TIAL1 Recombinant Protein**
TIAL1 (TIA1-like 1), also known as TIAR, is a member of the TIA1/TIAR protein family, characterized by RNA-binding activity and roles in post-transcriptional gene regulation. It contains three RNA recognition motifs (RRMs) that mediate interactions with AU-rich elements in mRNA, influencing splicing, stability, and translation. TIAL1 is widely expressed in eukaryotic cells and participates in stress response pathways by promoting the formation of stress granules (SGs), cytoplasmic aggregates that sequester non-translating mRNAs during cellular stress.
Recombinant TIAL1 protein is engineered for experimental studies to elucidate its molecular functions. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells*), it retains RNA-binding capacity and facilitates investigations into its role in mRNA metabolism, apoptosis, and immune signaling. Studies highlight its involvement in pathologies, including cancer and neurodegeneration. For example, TIAL1 dysregulation is linked to aberrant splicing in tumors and aggregation in neurodegenerative diseases like amyotrophic lateral sclerosis (ALS).
The recombinant protein is pivotal for *in vitro* assays, such as RNA-protein interaction studies, structural analyses, and drug screening. Its availability supports research into stress granule dynamics, offering insights into cellular adaptation mechanisms and potential therapeutic targets. By enabling precise manipulation of TIAL1 activity, recombinant tools advance understanding of its dual roles as a tumor suppressor or context-dependent oncogene, depending on cellular conditions. Overall, TIAL1 recombinant protein serves as a critical reagent for decoding its multifaceted contributions to cell biology and disease.
