A	PF21453	Infectious salmon anemia virus nucleoprotein, helical bundle (NCAP_ISAV_hel)	Infectious salmon anemia virus nucleoprotein, helical bundle	This entry represents the helical bundle of Infectious salmon anemia virus (ISAV) nucleoprotein that forms the head domain described in [1]. The head and body domains from this protein affect the equilibrium-state RNA binding.	Domain
A	PF21422	Orthomyxovirus nucleoprotein, C-terminal (NP_C_Orthomyx)	Orthomyxovirus nucleoprotein, C-terminal	This entry represents a domain found in the nucleoprotein from the orthomyxovirus Infectious salmon anemia virus [1]. This protein is similar to that in Influenza virus and consists of a head and a body domain [1]. This entry represents the tail loop ...	This entry represents a domain found in the nucleoprotein from the orthomyxovirus Infectious salmon anemia virus [1]. This protein is similar to that in Influenza virus and consists of a head and a body domain [1]. This entry represents the tail loop which plays a role in oligomerisation. It folds into an extended beta-hairpin that protrudes into a deep pocket in a neighbouring subunit to mediate dimer formation.	Domain
A	PF21451	Salmon anemia virus nucleoprotein N-terminal domain (NCAP_ISAV_N)	Salmon anemia virus nucleoprotein N-terminal domain	This entry represents the N-terminal domain of the Salmon anemia virus nucleoprotein which has an alpha/beta fold [1] consisting of three anti-parallel beta-strands and two alpha helices in an extended shape and interacts with the rest of the structu ...	This entry represents the N-terminal domain of the Salmon anemia virus nucleoprotein which has an alpha/beta fold [1] consisting of three anti-parallel beta-strands and two alpha helices in an extended shape and interacts with the rest of the structure [1]. This domain may regulate the dynamics of the NP RNA binding.	Domain
