How to use regexp to search for separated sequences?

Say I have a text file with tons of random letters and I want to search it for the sequence ABBA[AGTC]DABA I want ABBA and DABA to be on the ends of the sequence but also want a variable sequence in the middle. GAGA can be either 0, 4, or 6 letters and can be any combination of the letters AGTC.
Any idea how to search for such sequences using regexp? Maybe another search command?

Is the ‘variable sequence in the middle’ always enclosed within square brackets []?
Can you provide a sample sequence, or a file with some sample sequences, in the format you expect to use them?

Are you looking for something like this
>> regexp( 'ABBAAGTGTCDABA', 'ABBA([AGTC]{0}|[AGTC]{4}|[AGTC]{6})DABA', 'match' )
ans =
'ABBAAGTGTCDABA'
>> regexp( 'ABBADABA', 'ABBA([AGTC]{0}|[AGTC]{4}|[AGTC]{6})DABA', 'match' )
ans =
'ABBADABA'
>> regexp( 'xxxABBAAGTGTCDABAzzz', 'ABBA([AGTC]{0}|[AGTC]{4}|[AGTC]{6})DABA', 'match' )
ans =
'ABBAAGTGTCDABA'
