MBD3 | Methyl-CpG-binding domain protein 3; Acts as transcriptional repressor and plays a role in gene silencing. Does not bind to DNA by itself. Binds to DNA with a preference for sites containing methylated CpG dinucleotides (in vitro). Binds to a lesser degree DNA containing unmethylated CpG dinucleotides. Recruits histone deacetylases and DNA methyltransferases. (291 aa) | ||||
HYPK | Huntingtin-interacting protein K; Has a chaperone-like activity preventing polyglutamine (polyQ) aggregation of HTT. Protects against HTT polyQ-mediated apoptosis in Neuro2a neuronal cells. Regulator of the N-terminal acetyltransferase NAA10-NAA15 complex. Has been in one study shown to be required for optimal NAA10-NAA15 complex-mediated N-terminal acetylation. However, has been shown in another study to act in vitro as an inhibitor of NAA10-NAA15 complex-mediated N- terminal acetylation. (129 aa) |
