The three isoforms of mammalian Tet3 include Tet3FL, Tet3s, and Tet3o
The CXXC domain of Tet3 is a specific reader of 5-carboxylcytosine at CcaCG sequences
The crystal structure of the CXXC domain-5caC complex was solved
Tet3FL in neurons targets genes of the lysosome and base excision repair pathways
