Transglutaminase 1 (TGM1), a member of the transglutaminase enzyme family, plays a critical role in maintaining epidermal homeostasis and skin barrier function. This calcium-dependent enzyme catalyzes the cross-linking of structural proteins, such as involucrin and loricrin, during terminal differentiation of keratinocytes. By forming ε-(γ-glutamyl)lysine isopeptide bonds, TGM1 contributes to the assembly of the cornified cell envelope—a resilient protein-lipid layer essential for protecting against environmental stressors and preventing water loss.
Mutations in the TGM1 gene are linked to autosomal recessive congenital ichthyosis (ARCI), a group of severe skin disorders characterized by defective epidermal barrier formation, scaling, and susceptibility to infections. The absence or dysfunction of TGM1 disrupts cornification, leading to lifelong dermatological complications. This association has driven research into TGM1's molecular mechanisms and its potential as a therapeutic target.
Recombinant TGM1 protein, produced through heterologous expression systems like mammalian cells or bacteria, enables detailed study of its structure, enzymatic activity, and interactions. Purified recombinant TGM1 is used in biochemical assays, drug screening, and disease modeling. Recent advances aim to explore enzyme replacement therapies or gene-editing strategies for TGM1-deficient ichthyosis. Beyond dermatology, TGM1's cross-linking properties have applications in biomanufacturing, such as modifying biomaterials or stabilizing protein-based therapeutics.
Despite progress, challenges remain in delivering functional TGM1 to compromised skin tissue and ensuring long-term efficacy. Ongoing studies focus on optimizing recombinant protein stability, delivery vehicles (e.g., lipid nanoparticles), and preclinical validation. Understanding TGM1's role continues to bridge gaps between skin biology, genetic disorders, and translational innovation.
