A, D, G, J	PF00944	Alphavirus core protein (Peptidase_S3)	Alphavirus core protein	Also known as coat protein C and capsid protein C. This makes the literature very confusing. Alphaviruses consist of a nucleoprotein core, a lipid membrane which envelopes the core, and glycoprotein spikes protruding from the lipid membrane.	Domain
