Asymmetric cell division is intensely studied because it can generate cellular diversity as well as maintain stem cell populations. Asymmetric cell division requires mitotic spindle alignment with intrinsic or extrinsic polarity cues, but mechanistic detail of this process is lacking. Here we develop a method to construct cortical polarity in a normally unpolarized cell line, and use this method to characterize Partner of Inscuteable (Pins; LGN/AGS3 in mammals)-dependent spindle orientation. We identify a previously unrecognized evolutionarily-conserved Pins domain (PinsLINKER) that requires Aurora-A phosphorylation to recruit Discs large (Dlg; PSD-95/hDlg in mammals) and promote partial spindle orientation. The well-characterized PinsTPR domain has no function alone, but placing the PinsTPR in cis to the PinsLINKER gives dynein-dependent precise spindle orientation. This "induced cortical polarity" assay is suitable for rapid identification of the proteins, domains, and amino acids regulating spindle orientation or cell polarity.
