Protein: E3 ubiquitin-protein ligase TTC3 (EC 2.3.2.27) (RING-type E3 ubiquitin transferase TTC3) (TPR repeat protein D) (Mtprd) (O88196)
Organism: Mus musculus (Mouse)
Function: E3 ubiquitin-protein ligase which catalyzes the formation of 'Lys-48'-polyubiquitin chains (By similarity). Mediates the ubiquitination and subsequent degradation of phosphorylated Akt (AKT1, AKT2 and AKT3) in the nucleus (By similarity). Acts as a terminal regulator of Akt signaling after activation; its phosphorylation by Akt, which is a prerequisite for ubiquitin ligase activity, suggests the existence of a regulation mechanism required to control Akt levels after activation (By similarity). Positively regulates TGFB1-induced epithelial-mesenchymal transition and myofibroblast differentiation by mediating the ubiquitination and subsequent degradation of SMURF2 (By similarity). Regulates neuronal differentiation by regulating actin remodeling and Golgi organization via a signaling cascade involving RHOA, CIT and ROCK (By similarity). Inhibits cell proliferation (By similarity).
Subcellular location: Nucleus {ECO:0000250|UniProtKB:P53804}. Cytoplasm {ECO:0000250|UniProtKB:P53804}. Golgi apparatus {ECO:0000250|UniProtKB:D3ZSP7}. Note=Nuclear localization may be dependent on the proteolytic cleavage of full length protein in the cytoplasm (By similarity). This cleavage may reveal an N-terminal nuclear localization signal, allowing N-terminal fragments to enter the nucleus (By similarity). {ECO:0000250|UniProtKB:P53804}.
