Structural domains of olfactorin and anosmin-1 and analysis of their N-terminal region. |
Identification of olfactorin in COS-7 cells transfected with the pCMV Sport6.1-FLAG-BQ887653 mouse Umodl1 expression vector. |
Effects of the exposure to the olfactorin-enriched CM (olfactorinFLAG) on the chemomigration of GN11 cells. Microchemotaxis experiments were performed in the Boyden's chamber using the CM from COS-7 cells transfected with the empty vector (CM) or with pCMV SPORT6.1 PPT-FLAG-UMODL1 (the olfactorin-enriched CM; olfactorinFLAG) or pMT21myc- |
Effect of the ERK1/2 signaling pathway inhibitor on anaosmin-1- and olfactorinFLAG-induced GN11 chemomigration. GN11 cells were pretreated with ERK1/2 inhibitor U0126 (1 µM) and then to the exposed control CM, anosmin-1 |

Transcriptional analysis of olfactorin effects on GN11 cells. |
Potential interaction between the modeled human olfactorin structures with the resolved FGFR1-FGF2 complex (PDB code: 1FQ9) and its comparison with anosmin-1. As evidenced (red circles) WAP domains of olfactorin and anosmin-1 interact with the D2 domain of FGFR1 by assuming comparable arrangements. Greater differences are seen in the pose of the FNIII.1 domain; however, in both complexes it appears to conveniently approach the D2 domain of FGFR1. As shown in the left panel, the WAP-FGFR1 interactions appear to be mostly stabilized by ionic contacts. |
