Activity summary

SCRIBBLE also known as SCRIB or Scribble homolog is a protein that mainly functions in cell polarity and adhesion. It has a mass of about 215 kDa. SCRIBBLE interacts with other cellular structures to maintain apical-basal polarity. Researchers observe its expression in several tissue types especially in epithelial tissues where maintaining cell polarity is important. SCRIBBLE acts as a scaffold that links signaling molecules and components of membranes facilitating the organization of molecular assemblies on the plasma membrane.

Biological function summary

SCRIBBLE contributes significantly to cell orientation and tissue architecture. It is a critical component of the Scribble complex which also includes the proteins LGL1 and DLG1. This complex modulates cell junctions and the establishment of cell polarity. SCRIBBLE plays roles in processes such as wound healing and neural growth by modulating cell migration. It also influences epithelial-mesenchymal transition (EMT) a process important in development and cancer metastasis.

Pathways

SCRIBBLE is integral in the regulation of the Hippo signaling pathway. Proper function of this pathway is necessary for controlling organ size and suppressing tumorigenesis. SCRIBBLE interacts with proteins such as YAP and TAZ which act as transcriptional co-activators within the Hippo pathway. Additionally SCRIBBLE is linked to the Wnt signaling pathway where it interacts with Disheveled proteins impacting processes such as cell fate and proliferation.

Associated diseases and disorders

SCRIBBLE is implicated in cancer progression particularly in breast and colorectal cancers. Disruption in SCRIBBLE's function or expression can lead to loss of cell polarity and increased invasiveness contributing to tumor development. In breast cancer its interaction with the protein LATS2 in the Hippo pathway is important for controlling cell proliferation and apoptosis. Abnormal SCRIBBLE expression is also associated with neural tube defects where proper cell polarity and signaling are required for normal neural development.
