Yep:
geo5=# \df AsTopoJSON

                                      List of functions

   Schema  |    Name    | Result data type |          Argument data types 
   |  Type
----------+------------+------------------+----------------------------------------+--------
  topology | astopojson | text             | tg topogeometry, edgemaptable 
regclass | normal
(1 row)

geo5=# SHOW search_path;
         search_path
---------------------------
  "$user", public, topology


I was wrong on the name of the function, though: it is "AsTopoJson", without any 
"ST_AsTopoJson" alias.
