Q
what is the role of the nuclear pore complex? What is it made of?
A
gateway for proteins made in the cytoplasm to enter
Allow mRNA, tRNA and ribosomal subunits made in the nucleus to enter cytoplasm
made of proteins called nucleoporins
2
Q
What are the transport receptors for the nuclear pore complex called?
A
Importins and exportins
3
Q
what are 3 ways gene expression is controlled at translation level?
A
Initiation of translation : proteins that prevent translation
cytoplasmic localization: something about division across the body?
stability: proteins influencing longevity and stabilization of mRNA. removing cap & tail
4
Q
What is the function of proteasomes? What does it target to function?
A
Degradation of proteins
recognized ubiquitin on proteins to start degrading
