It is capitalized when referring to the Abrahamic God, and can be used in phrases such as 'In nome del Dio' (In the name of God) or 'La parola di Dio' (The word of God).
Thank God, it's Friday.

My God, I did not study for the exam.
This is a phrase individuals might use when they're taken by surprise or shocked about something -- such as realizing they forgot to study for an exam. 'Dio mio' is a direct translation of 'My God', and 'non ho studiato per l'esame' means 'I did not study for the exam'.
