Alignment, consensus and secondary structure of Spin/Ssty repeats. The upper part shows the alignment of Spin/Ssty repeats. A two-letter organism-specific code (mm, Mus musculus; hs, Homo sapiens; ol, Oryzias latipes; bt, Bos taurus; gg, Gallus gallus) appears on the far left of each line, followed by a protein identifier, the repeat subtype (type A, amino-terminal; type B, central; type C, carboxy-terminal), the database identifier, the start and end residue of the Spin/Ssty repeat in the protein and the protein sequence. Amino acids are colored according to an 80% consensus. h, hydrophobic (ACFGILMVWP, white letters on dark blue); l, aliphatic (ILV, cyan); p, polar (NQSTY, yellow); a, aromatic (FHWY, purple); -, acidic (ED, green); +, basic (HKR, red letters on yellow); t, tiny (GAS, gray). The secondary-structure predictions of various programs run by the Jpred2 server and the Jpred2 consensus prediction are presented below. E, β strand; H, α helix.
