TBCK

TBCK is a protein that contains a protein kinase domain, a Rhodanase-like domain and the Tre-2/Bub2/Cdc16 (TBC) domain. TBCK is thought to function in actin organization, cell growth and cell proliferation by regulating the mammalian target of the rapamycin (mTOR) signaling pathway. TBCK may also be involved in the transcriptional regulation of the components of the mTOR complex.

Midbody
Mainly localized in the cytoplasm during interphase. During metaphase, TBCK accumulates at the mitotic spindle. At the end of mitosis, it is detected at the midbody.

Hypotonia, infantile, with psychomotor retardation and characteristic facies 3 (IHPRF3):
An autosomal recessive neurodevelopmental disorder characterized by profound developmental disability, intellectual disability and severe hypotonia. Many patients have seizures, and show brain atrophy, dysgenesis of the corpus callosum and white-matter changes on neuroimaging. Non-specific facial dysmorphism is noted in some individuals.
