Summary: Enables PDZ domain binding activity; myosin binding activity; and protein serine/threonine kinase activity. Involved in several processes, including morphogenesis of an epithelium; oocyte differentiation; and positive regulation of plasma membrane bounded cell projection assembly. Located in apical cortex; apical plasma membrane; and apicolateral plasma membrane. Part of PAR polarity complex. Is active in apical junction complex. Is expressed in several structures, including epithelial cell; epithelium; germ layer; specialized Malpighian tubule cell; and stomodeal invagination. Used to study carcinoma and high grade glioma. Orthologous to several human genes including PRKCI (protein kinase C iota). [provided by Alliance of Genome Resources, Nov 2024]

aPKC helps to sharpen the pattern of Miranda, by keeping it off the apical and lateral cortex after nuclear envelope breakdown.
Title: A chemical-genetics approach to study the role of atypical Protein Kinase C in Drosophila.
Therefore, phosphorylation of Miranda by aPKC and differential binding to the actomyosin network are required at distinct phases of the cell cycle to polarize fate determinant localization in neuroblasts.
Title: aPKC-mediated displacement and actomyosin-mediated retention polarize Miranda in Drosophila neuroblasts.
Here we show that PTEN mutation impacts aPKC and Lgl protein levels also in Drosophila. Moreover, we demonstrate that PI3K activation is not sufficient to trigger tumourigenesis, while aPKC promotes hyperplastic growth of the neuroepithelium and a noticeable expansion of the type II neuroblasts.

The authors find that the tumor suppressor Discs large (Dlg) links the Par complex component atypical Protein Kinase C (aPKC) to the essential spindle orientation factor GukHolder (GukH).

We first demonstrate that Hook2 is essential for the polarized Golgi re-orientation towards the migration front. Depletion of Hook2 results in a decrease of PAR6alpha at the centrosome during cell migration, while overexpression of Hook2 in cells induced the formation of aggresomes with the recruitment of PAR6alpha, aPKC and PAR3
Title: Hook2, a microtubule-binding protein, interacts with Par6α and controls centrosome orientation during polarized cell migration.
