The Republic is undoubtedly influential in Western philosophy, but you won't find many contemporary political scientists or philosophers referencing it directly without a very heavy dose of qualification. In this context it's most often used as a primary historical work more than a philosophical one.

Pretty much the only time you will see someone engaging with it as a work of authoritative or relevant philosophy (and really, just, a handful of notable passages) is in the context of anti-liberal rhetoric which is intentionally exploiting the assumption that the reader does not have a broad background in contemporary politics, but might know the name "Plato."

It's kind of like the difference between quoting Newton in the context of general relativity, versus quoting Newton in support of the luminiferous aether.
