Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The LLGL1 and LLGL2 proteins also known as Lethal (2) giant larvae proteins play important roles in cell polarity and asymmetric cell division. LLGL1 has a molecular mass of approximately 130 kDa and is expressed in various tissues with notable presence in the brain and reproductive organs. LLGL2 shares similar distribution and expression patterns. These proteins structurally contain several WD40 repeats involved in protein-protein interactions that help them in functioning as cortical factors.
Biological function summary

In epithelial cells and neural progenitors LLGL1 and LLGL2 are essential for maintaining cell polarity contributing to the structural stability and function of tissues. Both proteins are part of the Scribble complex a multi-protein assembly that regulates cell polarity and adhesion. By ensuring proper orientation and polarization of cells they are involved in tissue homeostasis and developmental processes.

Pathways

Cell polarity and division control involves the LLGL1 and LLGL2 proteins. They are key components of the PAR (Partitioning-defective) pathway interplaying with proteins like aPKC and PAR-6 essential for spatial cellular orientation. Additionally they play a role in the Hippo signaling pathway which is important for organ size regulation and cell proliferation working alongside proteins such as YAP/TAZ.

Dysfunction or alterations in LLGL1 and LLGL2 proteins have associations with cancer and neurological disorders. Loss of function can contribute to tumorigenesis highlighting their role as tumor suppressors in various cancer studies. In the context of neurological disorders improper regulation linked with these proteins can provide insight into brain development diseases interacting with proteins like Scribble and DLG variants.
