A novel electrochemical detection method utilizing a cost-effective hybrid-modified electrode has been established. A glassy carbon (GC) modified electrode was tested for its ability to measure electrochemical tTG antibody levels, which are essential for diagnosing and monitoring Celiac disease (CD). Tissue transglutaminase protein biomolecules are immobilized on a quantum dots-polypyrrole nanocomposite in the improved electrode.

White-Sutton syndrome (WHSUS) is a rare neurodevelopmental disorder caused by heterozygous variants in the POGZ gene. With slightly over 100 reported cases, the diagnosis of WHSUS remains challenging due to its variable and non-specific clinical features. We report a novel case of WHSUS carrying a heterozygous de novo variant in the POGZ gene and with characteristic clinical features including global developmental delay, autism spectrum disorder, generalised myoclonic epilepsy, hypotonia and distinct dysmorphic features.

In this study, the effects of transglutaminase on the structural and physicochemical properties of soy protein isolate/konjac glucomannan complex were investigated. Additionally, the complex was treated with different transglutaminase additions, cross-linking temperatures, and cross-linking pH and compared with a control without transglutaminase to elucidate the effect of transglutaminase on the internal interactions within the complex. The results demonstrated that transglutaminase treatment significantly enhanced the water-holding and oil-binding capacities by 34.

Transglutaminase 2 (TG2) is a uniquely versatile protein with diverse catalytic activities, such as transglutaminase, protein disulfide isomerase, GTPase and protein kinase, and participates in several biological processes. According to information available in the RBP2GO database, TG2 can act as an RNA-binding protein (RBP). RBPs participate in posttranscriptional gene expression regulation, therefore influencing the function of RNA, whereas RNA molecules can also modulate the biological activity of RBPs.

This study aimed to prepare novel nanocomplexes for delivery of lutein using transglutaminase (TGase)-type glycation of casein. The effect of glycated casein nanoparticles on the environmental stability, bioavailability, and antioxidant properties of lutein was investigated. Glycated casein nanoparticles with uniform distribution and small particle size were successfully prepared by ultrasound technology.
