20534510-5	2010	The PDGF-B:PDGFRbeta interface is predominantly hydrophobic, and PDGFRs and the PDGF propeptides occupy overlapping positions on mature PDGFs, rationalizing the need of propeptides by PDGFs to cover functionally important hydrophobic surfaces during secretion.	propeptides	169-180	platelet derived growth factor subunit B	Homo sapiens	4-10
