Clathrin: A Protein with Multiple Functions

CELLS-RERU1N

Kinetochore fibers (K-fibers) are bundles of microtubules that form the mitotic spindle. The proper function of the mitotic spindle requires that each K-fiber has its microtubules bound together with the help of clathrin.

What other function(s) do(es) clathrin serve in the cell?

Select ALL that apply.

A

Axonal transport.

B

Protein degradation in the nucleus.

C

Vesicular budding from the Golgi apparatus

D

Membrane recycling following vesicular release at the synapse

E

Endocytosis
