Activity summary

Integrin alpha 3 also known as ITGA3 or alpha 3 is a protein that plays an important role in cell adhesion and signaling. It forms complexes with other integrins to mediate interactions between cells and the extracellular matrix. Integrin alpha 3 is a type I transmembrane protein with a molecular weight of approximately 120 kDa. This protein is primarily expressed in epithelial tissues including the skin kidneys and respiratory tract.

Biological function summary

Integrin alpha 3 functions as a cell surface receptor that helps regulate cell migration proliferation and differentiation. It is a part of the alpha-3-beta-1 integrin complex which interacts with extracellular proteins like laminin-5 and collagen. This interaction facilitates the transmission of signals from the outside to the inside of the cell affecting various cellular responses and activities.

Pathways

Integrin alpha 3 plays a significant role in the cell signaling and communication pathways. It is involved in the pathways like focal adhesion and MAPK signaling. In these pathways integrin alpha 3 interacts with other proteins such as paxillin and FAK (focal adhesion kinase) which are critical for the downstream signaling that regulates cell shape and movement.

Associated diseases and disorders

Integrin alpha 3 is linked to conditions like skin blistering diseases and cancers particularly those affecting the epithelial tissues. Alterations in integrin alpha 3 expression or function can disturb cell adhesion leading to diseases like epidermolysis bullosa. Additionally in cancer integrin alpha 3 often collaborates with proteins like MMP-9 to promote tumor invasion and metastasis.
