>PF00023 Ank: Ankyrin repeat Hereditary spherocytosis; InterPro: IPR002110 The ankyrin repeat is one of the most common protein-protein interaction motifs in nature
Ankyrin repeats are tandemly repeated modules of about 33 amino acids. They occur in a large number of functionally diverse proteins mainly from eukaryotes. The few known examples from prokaryotes and viruses may be the result of horizontal gene transfers []. The repeat has been found in proteins of diverse function such as transcriptional initiators, cell-cycle regulators, cytoskeletal, ion transporters and signal transducers. The ankyrin fold appears to be defined by its structure rather than its function since there is no specific sequence or structure which is universally recognised by it. The conserved fold of the ankyrin repeat unit is known from several crystal and solution structures [, , , ]. Each repeat folds into a helix-loop-helix structure with a beta-hairpin/loop region projecting out from the helices at a 90o angle. The repeats stack together to form an L-shaped structure [, ].; GO: 0005515 protein binding; PDB: 1D9S_A 1NFI_F 1IKN_D 1WDY_A 1OT8_C 1QYM_A 1TR4_A 1UOH_A 1N11_A 1K1A_A ....
>PF00515 TPR_1: Tetratricopeptide repeat; InterPro: IPR001440 The tetratrico peptide repeat (TPR) is a structural motif present in a wide range of proteins [, , ]
It mediates protein-protein interactions and the assembly of multiprotein complexes []. 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. The X-ray structure of a domain containing three TPRs from protein phosphatase 5 revealed that TPR adopts a helix-turn-helix arrangement, with adjacent TPR motifs packing in a parallel fashion, resulting in a spiral of repeating anti-parallel alpha-helices []. The two helices are denoted helix A and helix B. The packing angle between helix A and helix B is ~24 degrees; within a single TPR and generates a right-handed superhelical shape. Helix A interacts with helix B and with helix A' of the next TPR. Two protein surfaces are generated: the inner concave surface is contributed to mainly by residue on helices A, and the other surface presents residues from both helices A and B. ; GO: 0005515 protein binding; PDB: 3SF4_C 2LNI_A 1ELW_A 2C0M_A 1FCH_B 3R9A_B 2J9Q_A 2C0L_A 1KT1_A 3FWV_A ....
