A, B	PF02080	TrkA-C domain (TrkA_C)	TrkA-C domain	This domain is often found next to the Pfam:PF02254 domain. The exact function of this domain is unknown. It has been suggested that it may bind an unidentified ligand [1]. The domain is predicted to adopt an all beta structure [1].	Domain
A, B	PF02254	TrkA-N domain (TrkA_N)	TrkA-N domain	This domain is found in a wide variety of proteins. These protein include potassium channels Swiss:P31069, phosphoesterases Swiss:Q59027, and various other transporters. This domain binds to NAD.	Domain
