A PF00063 Myosin_head Myosin head (motor domain) Domain PFAM PF00063
A PF00435 Spectrin Spectrin repeat Domain Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference [2]. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteristic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in ultiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated. PFAM PF00435
A PF02736 Myosin_N Myosin N-terminal SH3-like domain Domain This domain has an SH3-like fold. It is found at the N-terminus of many but not all myosins. The function of this domain is unknown. PFAM PF02736
