A polyubiquitin promoter regulates expression of mutant Tbce cDNA (GM13256 clone) tagged at the C-terminal with GFP. The Tbce cDNA contains deletion of four amino acids downstream of the GKHN motif, to mimic the mutation found in human patients with Hypoparathyroidism-retardation-dysmorphism (HRD) syndrome.
Analogous mutation in human TBCE implicated in Hypoparathyroidism-retardation-dysmorphism syndrome; mutation carried on in vitro construct.
