* NY insurance superintendent to resign, will teach

* Dinallo seen as possible attorney general candidate

* Governor's office has no comment on successor (Adds comments, background)

NEW YORK, May 28 (Reuters) - New York state Insurance Superintendent Eric Dinallo will resign effective July 3, Governor David Paterson said on Thursday, amid speculation the former prosecutor may run for state attorney general.

Dinallo, who was a top aide to former Democratic Governor Eliot Spitzer when he was state attorney general, will become a visiting finance professor at New York University's Stern School of Business, Paterson said in a statement.

New York's insurance chief is the most prominent of U.S. state insurance regulators given New York's position as America's financial capital. And Dinallo's profile has been particularly high given the integral role he has played in the near-meltdown of insurer American International Group (AIG.N: Quote, Profile, Research) and other areas of the credit meltdown.

"He has been superintendent during one of the most turbulent times ever, and he has done an exceptional job," said Howard Mills, who was New York's insurance regulator before Dinallo.

Mills, who is now chief adviser for the insurance industry group at accounting firm Deloitte, added that Dinallo's performance as insurance regulator will open many doors to him in both the public and private sectors.

In 2003, Dinallo left the attorney general's office, becoming managing director of regulatory affairs at Morgan Stanley. In 2006 was named general counsel for insurance broker Willis Group Holdings (WSH.N: Quote, Profile, Research).
