TBCK-related encephalopathy (TBCKE) is a neurodevelopmental disorder associated with biallelic mutations in TBCK. Despite the increasing number of reported cases worldwide, the biochemical and biophysical properties of TBCK remain unclear, hindering molecular understanding of its role in disease. Here, we present the successful expression, purification, and biochemical characterization of full-length human TBCK produced in Spodoptera frugiperda cells. Biochemical and biophysical analyses reveal that the catalytically inactive pseudokinase domain of TBCK lacks nucleotide binding, consistent with the absence of the canonical VAIK, HRD, and DFG motifs required for catalysis. These findings support that TBCK is a class I pseudokinase and provide a foundation for future structural and functional studies to elucidate its biological role.
