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 | |
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 |
