Regex to capture 2 bits of data in - ABC:(anything)

Question

I need to parse (extract data - don't need to replace anything).

Test string: MAIN_HEADER:(ANOTHER_HEADER([DUMDUM:(BAH_123),OOPS,YEAH:(GAGA)])) need to output:

• First component: MAIN_HEADER - only caps alpha and underscore

• Second component: ANOTHER_HEADER:([DUMDUM:(BAH_123),OOPS,YEAH:(GAGA)]) - caps alpha, numbers, square and round brackets, commas, colons in any combination

I can extract second component with ^\(([a-zA-Z0-9_:,\(\)\[\]]*)\)$ but I don't know how to do 2 different matches to split components.
