What is PtK cell?

PtK2 cells are a cell line derived from male long-nosed potoroo (Potorous tridactylis) epithelial kidney cells. This cell line is used for a variety of applications in biomedical research but is particularly popular as a model for mitosis.

What is FAK gene?

Focal adhesion kinase (FAK), a non-receptor tyrosine kinase, is the first intracellular step in the signal transduction cascade initiated by the attachment of an integrin to the extracellular matrix at points known as focal adhesions. FAK has a key role in cellular migration and motility.

Is Ilk a kinase?

Since its discovery, ILK has been associated with multiple cellular functions including cell migration, proliferation, and adhesion. Integrin-linked kinases (ILKs) are a subfamily of Raf-like kinases (RAF).

What is FAK pathway?

FAK activity elicits intracellular signal transduction pathways that promote the turn-over of cell contacts with the extracellular matrix, promoting cell migration. FAK is required during development, with loss of FAK resulting in lethality.

What is the difference between focal adhesions and Hemidesmosomes?

Cells attach to the underlying extracellular matrix through two types of integrin-dependent junctions: focal adhesions, which attach the actin cytoskeleton to fibers of fibronectin, and hemidesmosomes, which connect intermediate filaments to basal laminae (Figure 22-9).

What is Ilk biology?

Integrin-linked kinase is an enzyme that in humans is encoded by the ILK gene involved with integrin-mediated signal transduction. Mutations in ILK are associated with cardiomyopathies. Since its discovery, ILK has been associated with multiple cellular functions including cell migration, proliferation, and adhesion.

What is FAK inhibitor?

FAK inhibitor GSK2256098 inhibits FAK, which may prevent the integrin-mediated activation of several downstream signal transduction pathways, including ERK, JNK/MAPK and PI3K/Akt, thereby inhibiting tumor cell migration, proliferation and survival, and tumor angiogenesis.

Is FAK a protein?

FAK is a cytoplasmic non-receptor protein tyrosine kinase that phosphorylates different targets in cells. FAK also has a very important position in cell signal transduction. It is the center of intracellular and extracellular signal transduction and mediates multiple signaling pathways.
