Moonlighting and pleiotropy among regulators of the degradation
... Multifunctional proteins are generally referred to as either pleiotropic or moonlighting proteins. Although define similarly, the meaning is these terms is quite different. While a moonlighting protein harbors several autonomous functions, pleiotropy refers to a single-functional protein, which infl ...

Thylakoid
A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum). Grana are connected by intergranal or stroma thylakoids, which join granum stacks together as a single functional compartment.
