Dorothy keeps record in storehouse (5)
I believe the answer is:
depot
'storehouse' is the definition.
(synonyms)
'dorothy keeps record' is the wordplay.
'dorothy' becomes 'dot' (nickname for someone called Dorothy).
'keeps' indicates putting letters inside.
'record' becomes 'ep'.
'dot' placed around 'ep' is 'DEPOT'.
'in' acts as a link.
(Other definitions for depot that I've seen before include "storeroom" , "Headquarters - storehouse" , "Storehouse, repository" , "(Military) store" , "Storehouse as for supplies" .)
