BACKGROUND Formation of epithelial sheets requires that cell division occurs in the plane of the sheet. During mitosis, spindle poles align so the astral microtubules contact the lateral cortex. Confinement of the mammalian Pins protein to the lateral cortex is essential for this process. Defects in signaling through Cdc42 and atypical protein kinase C (aPKC) also cause spindle misorientation. When epithelial cysts are grown in 3D cultures, misorientation creates multiple lumens.

JAM-A regulates cortical dynein localization through Cdc42 to control planar spindle orientation during mitosis
TLDR
Findings indicate that a PI(3)K- and cortical F-actin-dependent pathway of planar spindle orientation operates in polarized epithelial cells to regulate epithelial morphogenesis, and JAM-A is identified as a junctional regulator of this pathway. Expand
Discs Large Links Spindle Orientation to Apical-Basal Polarity in Drosophila Epithelia
TLDR
It is shown that Pins and Mud are also necessary for spindle orientation in follicle cells, as is the interaction between Dlg and Pins, a function that is separable from its role in epithelial polarity. Expand
Annexin A1 is a polarity cue that directs planar mitotic spindle orientation during mammalian epithelial morphogenesis
TLDR
This work identifies the membrane-associated protein Annexin A1 (ANXA1) as a novel interactor of LGN in mammary epithelial cells as an upstream cortical cue that regulates LGN to direct planar cell divisions during mammalian epithelial morphogenesis. Expand
EGFR controls IQGAP basolateral membrane localization and mitotic spindle orientation during epithelial morphogenesis
TLDR
The 3D‐MDCK model system is used to demonstrate a key role for a newly identified protein complex formed by IQGAP1 and the epithelial growth factor receptor (EGFR) in controlling the orientation of the mitotic spindle. Expand
Drosophila aPKC is required for mitotic spindle orientation during symmetric division of epithelial cells
TLDR
Drosophila aPKC is required in vivo for spindle planar orientation and apical exclusion of Pins (Raps) which suggests that the cortical cues necessary forSpindle orientation are not only conserved between DrosophILA and mammalian cells, but are also similar to those required for spindles apicobasal orientation during asymmetric cell division. Expand
Aurora A Triggers Lgl Cortical Release during Symmetric Division to Control Planar Spindle Orientation
TLDR
This work reveals that Lgl mitotic cortical release is not specifically linked to the asymmetric segregation of fate determinants, and proposes that Aurora A activation breaks the Dlg/Lgl interaction to allow planar spindle orientation during symmetric division via the Pins (LGN)/Dlg pathway. Expand
MISP regulates the IQGAP1/Cdc42 complex to collectively orchestrate spindle orientation and mitotic progression
TLDR
It is proposed that MISP regulates IQGAP1 and Cdc42 to ensure proper mitotic progression and correct spindle orientation and the localization of the dynactin subunit p150glued that is crucial for proper spindle positioning. Expand
Activation of Discs large by aPKC aligns the mitotic spindle to the polarity axis during asymmetric cell division
TLDR
This work establishes a molecular connection between the polarity and spindle orientation machineries during asymmetric cell division of Drosophila neuroblasts. Expand
Willin and Par3 cooperatively regulate epithelial apical constriction through aPKC-mediated ROCK phosphorylation
TLDR
A Willin/Par3–aPKC–ROCK pathway that controls epithelial apical morphology is uncovered and indicates that aPKC phosphorylates ROCK and suppresses its junctional localization, thereby allowing cells to retain normally shaped apical domains. Expand
Ect2/Pbl Acts via Rho and Polarity Proteins to Direct the Assembly of an Isotropic Actomyosin Cortex upon Mitotic Entry
TLDR
The data suggest that the release of Pbl/Ect2 from the nucleus at mitotic entry drives Rho-dependent activation of Myosin-II and induces a switch from Arp2/3 to Diaphanous-mediated cortical actin nucleation that depends on Cdc42, aPKC, and Par6. Expand

Mammalian Pins Is a Conformational Switch that Links NuMA to Heterotrimeric G Proteins
TLDR
It is proposed that a related switch mechanism might operate in asymmetric cell divisions in the fly and nematode by allowing LGN to interact simultaneously with both proteins, resulting in their cortical localization. Expand
Gαi generates multiple Pins activation states to link cortical polarity and spindle orientation in Drosophila neuroblasts
TLDR
Pins has multiple activity states that generate cortical polarity and link it with mitotic spindle orientation, and it is concluded that Pins forms a “closed” state via intramolecular GoLoco–tetratricopeptide repeat (TPR) interactions, which regulate Mud binding. Expand
aPKC Acts Upstream of PAR-1b in Both the Establishment and Maintenance of Mammalian Epithelial Polarity
TLDR
It is demonstrated that PAR-1b is essential for the asymmetric development of membrane domains of polarized MDCK cells, and mammalian aPKC functions upstream of PAR- 1b in both the establishment and maintenance of epithelial cell polarity. Expand
Microtubule-Induced Pins/Gαi Cortical Polarity in Drosophila Neuroblasts
TLDR
A role for microtubules is identified in polarizing the neuroblast cortex, a fundamental step for generating cell diversity through asymmetric cell division in Drosophila neuroblasts. Expand
Cdc42 controls spindle orientation to position the apical surface during epithelial morphogenesis
TLDR
It is concluded that Cdc42 regulates epithelial tissue morphogenesis by controlling spindle orientation during cell division by preventing the establishment of apical–basal polarity in individual cells but rather disruptsSpindle orientation, leading to inappropriate positioning of apICAL surfaces within the cyst.

aPKC Phosphorylation of Bazooka Defines the Apical/Lateral Border in Drosophila Epithelial Cells
TLDR
Although Baz acts as an aPKC targeting and specificity factor in nonepithelial cells, the results reveal that it performs a complementary function in positioning the adherens junction in epithelia. Expand
Identification of an Aurora-A/PinsLINKER/ Dlg Spindle Orientation Pathway using Induced Cell Polarity in S2 Cells
TLDR
A method to construct cortical polarity in a normally unpolarized cell line is developed and this method is used to characterize Partner of Inscuteable -dependent spindle orientation and identify a previously unrecognized evolutionarily conserved Pins domain (Pins(LINKER)); the well-characterized Pins(TPR) domain has no function alone. Expand
Rac1 orientates epithelial apical polarity through effects on basolateral laminin assembly
TLDR
It is reported that orientation of apical polarity in developing Madin–Darby canine kidney (MDCK) epithelial cysts requires the small GTPase Rac1 and the basement membrane component laminin and Rac1-mediated laminIn assembly in apical pole orientation. Expand
Par-3 mediates the inhibition of LIM kinase 2 to regulate cofilin phosphorylation and tight junction assembly
TLDR
It is reported that depletion of Par-3 elevates the phosphorylated pool of cofilin, a key regulator of actin dynamics, and identifies LIMK2 as a novel target ofPar-3 and uncover a molecular mechanism by which Par- 3 could regulateActin dynamics during cell polarization. Expand
Par-3 controls tight junction assembly through the Rac exchange factor Tiam1
TLDR
It is shown that depletion of Par-3 in mammalian epithelial cells profoundly disrupts tight junction assembly, and a novel mechanism through which Par- 3 engages in the spatial regulation of Rac activity and establishment of epithelial polarity is revealed. Expand
