6.7 animal extracellular matrix Flashcards
1
Q
main ingredient of the ECM
A
gylcoproteins
mostly collagen
2
Q
collagen
A
forms strong fibers outside the cells
3
Q
collagen fibers are in a network of woven
A
proteoglycans
4
Q
proteoglycans
A
has small core protein with lots of carbohydrate chains covlaently attached
5
Q
some cells are attached to the EC< by other ECM glycoproteins like
A
fibronectin
-attaches the ECM to integrins in the plasma membrane
6
Q
fibronectin
A
-attaches the ECM to integrins in the plans membrane
a protein that binds to receptor proteins called integrins
7
Q
scientist found that the ECM can influences
A
the activity of genes in the nucleus
regulate a cell’s behavior
-ECM communicates wit ha cell through integrins
8
Q
integrins
A
proteins going across cell membrane
- bind to ECM outside
- bind to cytoskeleton inside
- integrate changes occurring inside and outside the cell
