Molecular function

PDGF receptor activity, PDGF-activated receptor activity, PDGFR activity, platelet-derived growth factor-activated receptor activity

Combining with platelet-derived growth factor receptor ligand and transmitting the signal across the plasma membrane to initiate a change in cell activity.

Note that this term represents an activity and not a gene product, and should only be used when the receptor binds the ligand PDGF. For receptors that bind other growth factors, consider annotating to other terms under 'transmembrane signaling receptor activity ; GO:0004888.
