A, B, C	PF00906	Hepatitis core antigen (Hepatitis_core)	Hepatitis core antigen	The core antigen of hepatitis viruses possesses a carboxyl terminus rich in arginine. On this basis it was predicted that the core antigen would bind DNA [1]. There is some experimental evidence to support this [2].	Domain
