GRANT SUPPORT

Active

(8450) Shriners Research Program (Horton)                                                 1/1/07 – 12/31/09
Special Shared Facility:  Scientific Computing.
The goal of this Project is to provide cost effective computing resources in support of the research activities.
Role: PI

(8540) Shriners Research Program (Horton)                                                 1/1/05 – 12/31/07
FGFR3 Signaling in the cartilaginous growth plate               
This project is designed to delineate how wild type and mutant FGFR3 receptors are internalized, recycled and degraded by chondrocytes.
Role: PI

(8610) Shriners Research Program (Horton)                                                 1/1/06 – 12/31/08                   
Membrane signals target FGFR3 for degradation                                                                                        
The major goal is to delineate trafficking of endosomes carrying FGFR3 and determine how this trafficking and the lysosomal delivery activated FGFR3 to lysosomes are disturbed by mutations in achondroplasia.
Role:  PI

(8660) Shriners Research Program (Horton)                                                 1/1/05 – 12/31/07
COMP Trafficking in normal and pathological conditions
This project is designed to define the normal secretory pathway of COMP and determine how it is disturbed by mutation in pseudoachondroplasia.
Role: PI
