Activity summary

CD151 also known as PETA-3 or SFA-1 is a member of the tetraspanin family which are small membrane proteins with molecular mass of about 28 kDa. This protein is commonly expressed on various cells such as epithelial cells endothelial cells and platelets. CD151 is known to interact with integrins especially integrin α3β1 and α6β1 playing significant roles in cell adhesion and migration. It is mostly found in areas where cell-to-cell contact is vital for maintaining tissue integrity and cellular communication.

Biological function summary

CD151 engages in the stabilization of integrin complexes which facilitates signal transduction pathways that influence cellular behaviors like proliferation differentiation and survival. It does not function alone; CD151 is part of a tetraspanin-enriched microdomain (TEM) forming complexes that include proteins such as CD9 CD63 and other integrins. These complexes bring together structural and signaling molecules on the cell membrane creating platforms for efficient signal relay.

Pathways

CD151 plays a role in pathways involving cell adhesion and tissue repair. Notably it is involved in the integrin signaling pathway which is essential for cell-matrix interactions in tissues that require adhesion for repair or restructuring. CD151 interacts with proteins like PI3K and Akt within these pathways which are central to the signaling cascades regulating cellular responses to the extracellular environment.

Associated diseases and disorders

CD151 participation has been noted in cancer progression and metastasis. It links to the dysregulation observed in integrin functions such as those of integrin α3β1 which directly influences tumor cell invasion and metastasis in cancers like breast and prostate cancer. CD151 also exhibits connections with renal pathologies including Alport syndrome where the lack of functional basement membranes affects kidney function and it interacts with proteins like collagen IV in the disorder's progression.
