capsid

 [kap´sid]
the shell of protein that protects the nucleic acid of a virus; it is composed of structural units, or capsomers. According to the number of subunits possessed by capsomers, they are called dimers (2), trimers (3), pentamers (5), or hexamers (6).

cap·sid

(kap'sid),
Protein coat of a virus. See: virion.

capsid

(kăp′sĭd)
n.
The protein coat that constitutes the shell of a virus particle.

capsid

A protein coat that covers the nucleoprotein core or nucleic acid (RNA, DNA) of a free virus particle or phage, which may have icosahedral symmetry and itself be enclosed in an envelope—e.g., Togaviridae. It is composed of an integer multiple of 60 subunits, which self-assemble in a pattern typical for a particular virus.

vi·ri·on

(vī'rē-on)
The complete virus particle that is structurally intact and infectious.

capsid

The protein coat that encloses the genome of a virus.

capsid

the protein coat of a virus.

Capsid

The outer protein coat of a virus.

SDS-PAGE analysis of purified SINV-1 particles yields 3 major (VP1, VP2, VP3) and one minor (VP4) capsid proteins. N-terminal analysis has revealed the margins of the capsid proteins and the corresponding scissile bonds within the structural polyprotein (Valles and Hashimoto 2008).
Capsid proteins, and particularly the interfaces or seams where one connects to another, are very important for assembling and disassembling the HIV coat, said senior author Angela Gronenborn, Ph.D., chair, Department of Structural Biology, and director, University of Pittsburgh Center for HIV Protein Interactions.
Thus work on HPV prophylactic vaccines has focused on the viral capsid proteins L1 and L2.
