Abstract

The present invention provides a method of designing a modulator of a myosin, the method comprising molecular modeling of a compound such that the modeled compound interacts with at least three amino acid residues of said myosin, said residues being selected from (a) ranges K265-V268, V411-L441, N588-Q593, D614-T629, and V630-E646 of SEQ ID NO: 2, said myosin comprising or consisting of (i) the sequence of SEQ ID NO: 2; (ii) the sequence encoded by the sequence of SEQ ID NO: 1; (iii) a sequence being at least 40% identical to the sequence of SEQ ID NO: 2 or to the sequence encoded by the sequence of SEQ ID NO: 1; or (iv) a sequence encoded by a sequence being at least 40% identical to the sequence of SEQ ID NO: 1; wherein said sequence of (iii) or (iv) comprises said three amino acid residues, and wherein said residues comprise K265; or (b) ranges of any one of SEQ ID NOs: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106 or 108, respectively, said ranges aligning with the ranges of SEQ ID NO: 2 as defined in (a), said myosin comprising or consisting of (i) the sequence of any one of SEQ ID NO: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106 or 108, respectively; (ii) the sequence encoded by the sequence of any one of SEQ ID NO: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101, 103, 105, 107 or 109; respectively; (iii) a sequence being at least 40% identical to the sequence of any one of SEQ ID NO: 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106 or 108, respectively, or to the sequence encoded by the sequence of any one of SEQ ID NO: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101, 103, 105, 107 or 109, respectively; or (iv) a sequence encoded by a sequence being at least 40% identical to the sequence of any one of SEQ ID NO: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101, 103, 105, 107 or 109, respectively; wherein said sequence of (iii) or (iv) comprises said three amino acid residues, and wherein said residues comprise the residue aligning with K265 of SEQ ID NO: 2; thereby obtaining said modulator of a myosin.
