Phospholipase A 2 receptor 1 (PLA 2 R) mediates collagen‐dependent migration. The mechanisms by which PLA 2 R interacts with collagen remain unclear. We produced HEK293 cells expressing full‐length wild‐type PLA 2 R or a truncated PLA 2 R that lacks fibronectin‐like type II (FNII) domains or several regions of C‐type lectin‐like domain (CTLD). We show that the CTLD1–2 as well as the FNII domain of PLA 2 R are responsible for binding to collagen and for collagen‐dependent migration. Thus, multiple regions and domains of the extracellular portion of PLA 2 R participate in the responses to collagen. These data suggest a potentially new mechanism for PLA 2 R‐mediated biological response beyond that of a receptor for secretory PLA 2 .
