Does proteins include compounds that cells use as a ready source of energy? to store energy? to store genetic information?

Proteins are not used to store energy. Energy is stored in the form of carbohydrates (glycogen, for example) or fat. Genetic information is stored only in DNA. Proteins are what enzymes are made of. Proteins also functions as structural proteins: myosin and actin, membrane consituents, keratin and collagen, for example.
