Professor is a job title, and a title earned by having the job. It does not apply to lecturers or educators who have not been given the title.
Assistant Professors are professors, and have the title.
Many students will refer to you as professor simply because "doctor" or your first name will seem awkward. In my years of teaching at a University as a non-professor, I eventually gave up correcting it. But I would never use the title myself, because it is not correct.
