pfam16580: Astro_capsid_p2 (This model is not part of the current CDD release)
C-terminal tail of astrovirus capsid projection or spike
Astro_capsid_p2 is a family of turkey astroviral spike projections. These are globular domains on the surface of the viral capsid. Astroviruses cause diarrhoea in a variety of mammals and birds, and are small, non-enveloped, single-stranded RNA viruses. The spike carries three conserved patches on its surface which could be candidates for avian receptor-binding sites.
