A, B, C	PF02412	Thrombospondin type 3 repeat (TSP_3)	Thrombospondin type 3 repeat	The thrombospondin repeat is a short aspartate rich repeat which binds to calcium ions. The repeat was initially identified in thrombospondin proteins that contained 7 of these repeats [1]. The repeat lacks defined secondary structure [2].	Domain
A, B, C	PF05735	Thrombospondin C-terminal region (TSP_C)	Thrombospondin C-terminal region	This region is found at the C-terminus of thrombospondin and related proteins.	Domain
