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 multiple 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.	Domain
A	PF02736	Myosin N-terminal SH3-like domain (Myosin_N)	Myosin N-terminal SH3-like 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.	Domain
