Difference between proton and antiproton

I know you can have that they have opposite charges.

Could you also have the fact that a proton is made of quarks and antiprotons are made of antiquarks?

Yup.

Proton: Baryon, 2 up-quarks, 1 down-quark.

Antiproton: Antibaryon, 2 up-antiquarks, 1 down-antiquark

Same mass, same interactions, same spin, opposite charge.
