Meaning and Definition
The protein shell or capsid that encloses and protects the genetic material of a virus.
In virology and molecular biology, the structural protein that forms the outer protective layer (capsid) of a virus particle, often playing a crucial role in host cell recognition and entry. By extension, in certain contexts, the term may refer to a protein that forms a protective coating or layer around another structure within a cell.

Common Mistakes When Using “coat protein”

- Incorrect pluralisation: 'coat protein' is the singular form; the plural is 'coat proteins'.
FAQ
Frequently Asked Questions
Very closely related. The capsid is the overall protein shell structure, which is composed of multiple copies of one or more types of coat protein. 'Coat protein' often refers to the individual protein subunits that build the capsid.
No, it is specific to viruses. Bacteria have cell walls made of different materials (like peptidoglycan), not a protein coat in this sense.
Because the coat protein is on the outside of the virus, it is the part most easily recognised by the immune system. Vaccines often use isolated coat proteins (or genetic instructions to make them) to train the body's defences without using the whole, infectious virus.
It is an open compound noun, written as two separate words. It is sometimes hyphenated ('coat-protein') when used as a modifier before another noun (e.g., 'coat-protein gene'), but the two-word form is standard.
The protein shell or capsid that encloses and protects the genetic material of a virus.
Coat protein is usually technical/scientific in register.
Coat protein: in British English it is pronounced /ˈkəʊt ˌprəʊ.tiː.ɪn/, and in American English it is pronounced /ˈkoʊt ˌproʊ.tiː.ɪn/. Tap the audio buttons above to hear it.
