23209741 PTK7 is a novel marker of epithelial to mesenchymal transitions
23095747 cleavage of the PTK7 ectodomain by an ADAM proteinase was coupled with the membrane type-1 matrix metalloproteinase (MT1-MMP) cleavage of the PKP(621) downward arrowLI site in the seventh Ig-like domain of PTK7.

20837484 Results indicate that PTK7 is a major target of MT1-MMP.
20558616 PTK7 is a planar cell polarity component expressed in the myeloid progenitor compartment that conveys promigratory and antiapoptotic signals into the cell and represents an independent prognosis factor in patients treated with induction chemotherapy.
18471990 PTK7 plays an important role not only in tube formation, migration, and invasion of endothelial cells but also in angiogenesis.
17671748 mechanism of PTK7 upregulation in colorectal cancer
15683231 Lack of a thermodynamically meaningful self-association propensity for the CCK4 transmembrane domains demonstrates that the conserved GxxxG motif is not sufficient to drive CCK4 transmembrane helix-helix interactions.
