Integrin alpha 9 also known as alpha-nine or alpha-9 is a transmembrane protein that is part of the integrin family. It typically forms dimer with beta-1 integrin subunit. This protein has an approximate mass of 150 kDa. Integrin alpha 9 is expressed in various tissues with notable levels in the epithelial cells smooth muscle cells and leukocytes. Its primary mechanical role involves mediating cell adhesion and signaling by interacting with the extracellular matrix (ECM) components and some specific ligands.

Biological function summary

Integrin alpha 9 influences cell migration proliferation and survival through its interactions with ECM proteins like tenascin-C and osteopontin. It does not function alone; it forms part of a complex that includes various signaling molecules and cytoskeletal proteins. These associations facilitate communication between the cell cytoskeleton and the ECM influencing processes like wound healing and inflammation.

Pathways

Integrin alpha 9 plays roles in pathways such as the integrin signaling pathway and the focal adhesion pathway. It interacts closely with molecules like focal adhesion kinase (FAK) and Paxillin which are critical within these pathways. These relationships allow integrin alpha 9 to modulate cellular responses such as spreading migration and cellular structural organization.

Integrin alpha 9 has connections with conditions such as asthma and cancer. In asthma its interaction with ECM proteins contributes to inflammation and airway remodeling. In cancer altered expression and signaling through integrin alpha 9 can influence tumor growth and metastasis. The protein's involvement in disease processes often interacts with other integrins and receptors that regulate inflammation and cellular migration such as certain cytokine receptors.
