post translational modification: DOPA?

[Eric E. Snyder]

I heard an interesting talk last night... just in passing,
the speaker mentioned an invertebrate protein containing
17% dihydroxyphenylalanine (aka DOPA)!  I couldn't believe
this... 

Have I been living under a rock for the last 25 yrs?

How common is this protein modification?

Is it post-translational?

Does it occur in vertebrates?
