<p>The tetratrico peptide repeat (TPR) is a structural motif present in a wide range of proteins [<cite idref="PUB00005443"/>, <cite idref="PUB00001313"/>, <cite idref="PUB00005695"/>]. It mediates protein-protein interactions and the assembly of multiprotein complexes [<cite idref="PUB00014195"/>]. The TPR motif consists of 3-16 tandem-repeats of 34 amino acids residues, although individual TPR motifs can be dispersed in the protein sequence. Sequence alignment of the TPR domains reveals a consensus sequence defined by a pattern of small and large amino acids. TPR motifs have been identified in various different organisms, ranging from bacteria to humans. Proteins containing TPRs are involved in a variety of biological processes, such as cell cycle regulation, transcriptional control, mitochondrial and peroxisomal protein transport, neurogenesis and protein folding.</p><p>This repeat includes outlying Tetratricopeptide-like repeats (TPR) that are not matched by <db_xref db="INTERPRO" dbkey="IPR001440"/>.</p> Tetratricopeptide TPR2
