May one interrupt Pesukei D'Zimra for a mitzvah purpose (e.g., fulfilling Kriat Shema before its time expires, receiving a Torah aliyah, reciting blessings)?

Synopsis

The Rema prohibits interruption even for mitzvah between Baruch She'amar and Yishtabach. The Mishnah Berurah permits interruption for Kriat Shema lest its time expire, for Birkat HaTorah if forgotten, and for an aliyah under certain conditions. The Biur Halacha and Aruch HaShulchan discuss a broader range.
