Kobe Bryant was also voted to start as West guard, though his participation is in jeopardy because of a torn right rotator cuff.
Meanwhile, Pau and Marc Gasol have been voted the first brothers to start in the NBA All-Star game, while Toronto's Kyle Lowry made a late surge in fan balloting and will start for the Eastern Conference.
Lowry passed Dwyane Wade and will start alongside Washington's John Wall, the first time the East has had two first-time starters at guard since 2000.
Pau Gasol of Chicago will start up front for the East, along with James and Carmelo Anthony for the Feb. 15 game in New York.
Memphis' Marc Gasol joins New Orleans' Anthony Davis and the Clippers' Blake Griffin in the West front court.
Tom and Dick Van Arsdale played in the 1970 and 1971 games, but the Gasols -- once traded for each other -- are the first brothers chosen to start.
Both were among the leaders in all the balloting updates, but Lowry was running more than 100,000 votes behind Wade, a perennial All-Star and fan favorite, when the last results were released.
Fans rewarded him for his hard-nosed play in leading the Raptors to a huge lead in the Atlantic Division with his first All-Star appearance.
The East hasn't had both its guards making their first start since Philadelphia's Allen Iverson and Charlotte's Eddie Jordan in 2000.
Fans had to vote for two guards and three frontcourt players. The reserves will be picked by the head coaches in each conference and be announced next Thursday.
The star of the NBA-leading Golden State Warriors, Curry ended up with more than 1.5 million votes, more than 42,000 ahead of James, who had a 13,285-vote lead over the sharpshooter at the last update. Curry, who just two years ago was an All-Star snub, becomes the first Warriors player elected to consecutive starts since Chris Mullin in 1991-92.
The Warriors are off to a franchise record start of 34-6.
His partner in the All-Star backcourt is up in the air after the Lakers revealed Bryant's injury earlier Thursday. Though the severity of the injury is unknown, many rotator cuff injuries require surgery and several months of rehabilitation.
That could rule Bryant out of his 17th All-Star appearance, second all-time behind Kareem Abdul-Jabbar's 19. Bryant's first was in 1998 at Madison Square Garden, the site of this year's game.
Commissioner Adam Silver would name an injury replacement if needed, and coaches Steve Kerr (Golden State) of the West and Mike Budenholzer (Atlanta) of the East would determine who replaces an injured player in the starting lineup.
