**Background of Recombinant Human TIM14 Protein**
TIM14 (also known as HSPA9 or mortalin) is a mitochondrial chaperone protein critical for maintaining cellular homeostasis. It belongs to the heat shock protein 70 (HSP70) family and plays a central role in protein import into the mitochondrial matrix by interacting with the TIM23 translocase complex. TIM14 facilitates the ATP-dependent translocation and folding of nascent polypeptides, ensuring proper maturation of mitochondrial proteins. It also participates in stress response, apoptosis regulation, and quality control of misfolded proteins.
Dysregulation of TIM14 is implicated in neurodegenerative diseases, cancer, and aging. For instance, its overexpression is observed in certain cancers, promoting cell proliferation and evading apoptosis, while mutations are linked to neurodegenerative disorders like Parkinson’s disease. Recombinant human TIM14 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), retains these functional properties and is widely used to study mitochondrial import mechanisms, chaperone activity, and disease pathways *in vitro*. Its application spans structural studies, drug screening, and functional assays to explore therapeutic interventions targeting mitochondrial dysfunction.
