CENP-T is a family of vertebral kinetochore proteins that associates directly with CENP-W. The N-terminus of CENP-T proteins interacts directly with the Ndc80 complex in the outer kinetochore. Importantly, the CENP-T-W complex does not directly associate with CENP-A, but with histone H3 in the centromere region. CENP-T and -W form a hetero-tetramer with CENP-S and -X and bind to a ~100 bp region of nucleosome-free DNA forming a nucleosome-like structure. The DNA-CENP-T-W-S-X complex is likely to be associated with histone H3-containing nucleosomes rather than with CENP-nucleosomes. This domain is the C-terminal histone fold domain of CENP-T, which associates with chromatin [2-3].

This is the C-terminal domain found in eukaryotic UCH37 proteins (also known as Ubiquitin carboxyl-terminal hydrolase isozyme L5, UCHL5). UCH37 is a subunit of two complexes: INO80, which performs ATP-dependent sliding of nucleosomes for transcriptional regulation and DNA repair, and the 26S proteasome, which performs ATP-dependent proteolysis of polyubiquitylated proteins in the cytosol and nucleus. Recruitment to the proteasome is mediated by the C-terminal domain of RPN13 (also known as ADRM1). Recruitment to INO80 is mediated by the N-terminal domain of NFRKB. Structural and biochemical analysis reveal that RPN13 and NFRKB make similar interactions with the UCH37 C-terminal domain but have very different interactions with the catalytic UCH domain that are activating in the case of RPN13 and highly inhibitory in the case of NFRKB [3].
This family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260). A number of them are thought to carry ...
This family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260). A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5].
