The Role of TGM2 as a Drug Target and Biomarker: Unlocking New Avenues in Disease Treatment

In recent years, transglutaminase 2 (TGM2) has emerged as a promising drug target and biomarker, opening up new possibilities for the development of novel therapeutics and diagnostic tools. TGM2, also known as tissue transglutaminase, is a multifunctional enzyme involved in various cellular processes such as cell adhesion, apoptosis, and immune response modulation. This article explores the significance of TGM2 as a drug target and biomarker, shedding light on its potential applications in the field of medicine.

The Role of TGM2 as a Drug Target

As a drug target, TGM2 shows tremendous potential due to its involvement in disease pathogenesis and progression. Numerous studies have established a link between TGM2 overexpression and the development of various diseases, such as cancer, neurodegenerative disorders, inflammation, and fibrosis. TGM2 contributes to these disease processes by promoting cell survival, migration, and extracellular matrix deposition. Consequently, inhibiting TGM2 activity emerges as an attractive strategy to impede disease progression.

One notable area where the targeting of TGM2 shows promise is cancer therapy. TGM2 plays a crucial role in enhancing the aggressive behavior of cancer cells, including their invasiveness and resistance to chemotherapy. By targeting TGM2, researchers aim to develop more effective therapies that can inhibit cancer cell growth, enhance the efficacy of existing treatments, and prevent metastasis. Several TGM2 inhibitors have already demonstrated encouraging results in preclinical studies, highlighting the potential of TGM2 as a drug target in cancer treatment.

Beyond cancer, TGM2 also holds promise in the context of neurodegenerative disorders. Research suggests that TGM2 contributes to the accumulation of neurotoxic proteins, such as amyloid-beta and tau, which are characteristic of Alzheimer's disease. Inhibiting TGM2 may help reduce the formation of these toxic protein aggregates, potentially slowing down the progression of neurodegenerative diseases.

The Potential of TGM2 as a Biomarker

In addition to its role as a drug target, TGM2 is gaining recognition as a biomarker with diagnostic and prognostic value. Biomarkers are measurable indicators that provide valuable information about the presence and severity of a disease. TGM2 has shown promise as a biomarker in various diseases, offering insights into disease progression and patient response to treatment.

In cancer, TGM2 levels have been found to correlate with tumor size, stage, and metastatic potential. Studies have shown that elevated TGM2 expression in tumor tissues is associated with poorer prognosis, shorter survival rates, and increased resistance to therapy. Monitoring TGM2 levels could aid in early detection and treatment monitoring, guiding clinicians in tailoring therapies for better patient outcomes.

TGM2 has also shown potential as a biomarker in fibrotic diseases, such as liver fibrosis and pulmonary fibrosis. In these conditions, TGM2 expression levels correlate with disease severity and progression. Measuring TGM2 levels in patients may help assess disease progression and provide valuable information for treatment decisions, such as the initiation of antifibrotic therapies.

Challenges and Future Perspectives

While the potential of TGM2 as a drug target and biomarker is promising, several challenges remain. First, developing specific inhibitors that selectively target TGM2 without affecting other transglutaminase family members is critical to minimize off-target effects. Additionally, optimizing drug delivery systems to efficiently target TGM2 in a disease-specific manner is essential for successful clinical translation.

Furthermore, the practical implementation of TGM2 as a biomarker requires the development of accurate and reliable detection methods. Efforts are underway to establish standardized assays, such as enzyme-linked immunosorbent assays (ELISAs), for TGM2 quantification in biosamples, which would enable its integration into routine clinical practice.

In conclusion, TGM2 represents a promising drug target and biomarker with significant potential across a range of diseases. By targeting TGM2, researchers hope to develop more effective therapies and diagnostic tools, ultimately improving patient outcomes. However, further research and development are needed to fully exploit the therapeutic and diagnostic potential of TGM2, bringing us one step closer to personalized medicine and precision healthcare.

Protein Name: Transglutaminase 2

Functions: Calcium-dependent acyltransferase that catalyzes the formation of covalent bonds between peptide-bound glutamine and various primary amines, such as gamma-amino group of peptide-bound lysine, or mono- and polyamines, thereby producing cross-linked or aminated proteins, respectively (PubMed:9252372, PubMed:23941696, PubMed:31991788). Involved in many biological processes, such as bone development, angiogenesis, wound healing, cellular differentiation, chromatin modification and apoptosis (PubMed:1683874, PubMed:7935379, PubMed:9252372, PubMed:27270573). Acts as a protein-glutamine gamma-glutamyltransferase by mediating the cross-linking of proteins, such as ACO2, HSPB6, FN1, HMGB1, RAP1GDS1, SLC25A4/ANT1, SPP1 and WDR54 (PubMed:23941696, PubMed:24349085, PubMed:29618516, PubMed:30458214). Under physiological conditions, the protein cross-linking activity is inhibited by GTP; inhibition is relieved by Ca(2+) in response to various stresses (PubMed:7649299, PubMed:7592956, PubMed:18092889). When secreted, catalyzes cross-linking of proteins of the extracellular matrix, such as FN1 and SPP1 resulting in the formation of scaffolds (PubMed:12506096). Plays a key role during apoptosis, both by (1) promoting the cross-linking of cytoskeletal proteins resulting in condensation of the cytoplasm, and by (2) mediating cross-linking proteins of the extracellular matrix, resulting in the irreversible formation of scaffolds that stabilize the integrity of the dying cells before their clearance by phagocytosis, thereby preventing the leakage of harmful intracellular components (PubMed:7935379, PubMed:9252372). In addition to protein cross-linking, can use different monoamine substrates to catalyze a vast array of protein post-translational modifications: mediates aminylation of serotonin, dopamine, noradrenaline or histamine into glutamine residues of target proteins to generate protein serotonylation, dopaminylation, noradrenalinylation or histaminylation, respectively (PubMed:23797785, PubMed:30867594). Mediates protein serotonylation of small GTPases during activation and aggregation of platelets, leading to constitutive activation of these GTPases (By similarity). Plays a key role in chromatin organization by mediating serotonylation and dopaminylation of histone H3 (PubMed:30867594, PubMed:32273471). Catalyzes serotonylation of 'Gln-5' of histone H3 (H3Q5ser) during serotonergic neuron differentiation, thereby facilitating transcription (PubMed:30867594). Acts as a mediator of neurotransmission-independent role of nuclear dopamine in ventral tegmental area (VTA) neurons: catalyzes dopaminylation of 'Gln-5' of histone H3 (H3Q5dop), thereby regulating relapse-related transcriptional plasticity in the reward system (PubMed:32273471). Regulates vein remodeling by mediating serotonylation and subsequent inactivation of ATP2A2/SERCA2 (By similarity). Also acts as a protein deamidase by mediating the side chain deamidation of specific glutamine residues of proteins to glutamate (PubMed:9623982, PubMed:20547769). Catalyzes specific deamidation of protein gliadin, a component of wheat gluten in the diet (PubMed:9623982). May also act as an isopeptidase cleaving the previously formed cross-links (PubMed:26250429, PubMed:27131890). Also able to participate in signaling pathways independently of its acyltransferase activity: acts as a signal transducer in alpha-1 adrenergic receptor-mediated stimulation of phospholipase C-delta (PLCD) activity and is required for coupling alpha-1 adrenergic agonists to the stimulation of phosphoinositide lipid metabolism (PubMed:8943303)
