Summary
TTC3 (tetratricopeptide repeat domain 3, HGNC:12393) is a protein-coding gene on chromosome 21q22.13, encoding E3 ubiquitin-protein ligase TTC3 (P53804). E3 ubiquitin-protein ligase which catalyzes the formation of ‘Lys-48’-polyubiquitin chains.
Enables ubiquitin-protein transferase activity. Involved in protein K48-linked ubiquitination and ubiquitin-dependent protein catabolic process. Located in cytosol; nucleolus; and nucleoplasm.

Function. E3 ubiquitin-protein ligase which catalyzes the formation of ‘Lys-48’-polyubiquitin chains. Mediates the ubiquitination and subsequent degradation of phosphorylated Akt (AKT1, AKT2 and AKT3) in the nucleus. 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. Positively regulates TGFB1-induced epithelial-mesenchymal transition and myofibroblast differentiation by mediating the ubiquitination and subsequent degradation of SMURF2. Regulates neuronal differentiation by regulating actin remodeling and Golgi organization via a signaling cascade involving RHOA, CIT and ROCK. Inhibits cell proliferation.
Subunit / interactions. Interacts (when phosphorylated on Ser-378) with AKT1, AKT2 and AKT3 (when phosphorylated). Interacts with CIT. Interacts with POLG. Interacts with HSP70. Interacts with SMURF2.
Subcellular location. Nucleus. Cytoplasm. Golgi apparatus.
Tissue specificity. Found in all tissues examined.
Post-translational modifications. Phosphorylation on Ser-378 by Akt is required for ubiquitin ligase activity. Proteolytically cleaved into differently sized N- and C-terminal fragments.
Induction. Up-regulated by TGFB1 signaling.
Pathway. Protein modification; protein ubiquitination.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 73 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
