Give an example of a fibrous protein in the muscle

A

Filamentous actin protein

In myofibrils

2
Q

Micro tubule (tubulin) proteins are also fibrous. What are they made of

13 a helixes filaments

3
Q

What does tubulin do

A

It’s a protein which forms a tube from nucleus to membrane and allows transport of things like kinesin protein

Can also bind to anti cancer drugs

4

Titin is also a fibrous protein- what is its job

A

In the muscle it prevents filaments sliding too far out

A

Alanine and glycine interlocking

6
Q

A keratin is also a structural protein - in hair, nails etc. What is it made of

A

2 a helix coils

Can form disulfide bridges Eg in things like nails

7
