CCN3 as a moonlighting signaling protein: a potential model for dual nuclear and extracellular functions across the CCN family [PDF]

Cell Communication and Signaling
Originally identified in the 1990s as an extracellular matrix (ECM) protein, Cellular Communication Network factor 3 (CCN3) was recognized as a member of a structurally related family of six proteins sharing a conserved tetramodular organization and ...

Seasonal significance of new particle formation impacts on cloud condensation nuclei at a mountaintop location [PDF]

Atmospheric Chemistry and Physics, 2022
New particle formation (NPF) events are defined as a sudden burst of aerosols followed by growth and can impact climate by growing to larger sizes and under proper conditions, potentially forming cloud condensation nuclei (CCN).

The CCN family of genes: a perspective on CCN biology and therapeutic potential [PDF]

Journal of Cell Communication and Signaling, 2007
The CCN family of genes currently comprises six secreted proteins (designated CCN1-6 after Cyr61/CCN1; ctgf/CCN2; Nov/CCN3; WISP1/CCN4; WISP2/CCN5, WISP3/CCN6) with a similar mosaic primary structure. It is now well accepted that CCN proteins are not growth factors but matricellular proteins that modify signaling of other molecules, in particular those
