Cops are searching for a 31-year-old actress with a history of mental illness after she went missing from her Harlem apartment Sunday, police sources said.

Mabel Pantaleon was last seen at 9 a.m. Sunday on West 157th Street near Amsterdam Avenue, cops said yesterday.

She may be driving a silver 2004 Toyota Camry.

Pantaleon, who once appeared on the Showtime hit “Dexter,” left a nursing program in her last semester to pursue her dream of being an actress, according to her IMDB profile.

The sources said that Pantaleon suffers from manic depression and that no foul play is suspected.

She stands 5-foot-7 and weighs approximately 165 pounds, and has brown eyes and black hair.

She was wearing a red shirt with “Drake” on the front.
