Called Dan up about me (5)
I believe the answer is:
named
'called' is the definition.
('name' can be a synonym of 'call')
'dan up about me' is the wordplay.
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'about' means one lot of letters goes inside another.
'dan' written backwards gives 'nad'.
'nad' placed around 'me' is 'NAMED'.
(Other definitions for named that I've seen before include "Christened" , "Titled" , "Entitled" , "Identified by appellation" , "Handled" .)
