|
Definition
Tendon
Fiber
Fibril
tropcolagen
Procollagen |
|
|
Term
Describe collagen synthesis
|
|
Definition
- DNA transcribed in nucleus
- mRNA translated in RER to form pre-procollagen
- pre-procollagen modified in RERto form procollagen
- propeptides added to procollagen to prevent spontaneous formation inside cell
- procollagen exported to ECM, and propeptinase cleaves propeptides to allow formation of tropocollagen
