Connecticut Athletic Director Warde Manuel said the move will not affect his school's affiliation with the Big East.
"Our relationship is with the conference, and we'll look forward to working with the leadership in the conference to move forward," Manuel said.
Connecticut provided Marinatto with some of the conference's biggest moments during his tenure, winning national championships in men's basketball in 2011 and in women's basketball in 2009 and 2010.
But UConn had been actively exploring the possibility of joining the Atlantic Coast Conference or another conference after the moves by Syracuse and Pittsburgh.
Manuel said Monday that UConn has no current plans to leave.
"I'm happy in the Big East," he said. "That's where we're going to stay and compete and do what we do."
