Cell Junctions and Adhesion Molecules Flashcards
1
Q
Anchoring
A
Cell-Cell, Cell-Basal Lamina, Cell-ECM
Focal contact formed with ECM
2
Q
Occluding
A
Creates cell polarity
3
Q
Channel Forming
A
Passes chemicals between cells
4
Q
Signal Relaying
A
Neuronal junctions (i.e. gap junctions)
5
Q
Cadherins
A
Ca2+ dependent adhesion molecules
Forms desmosomes and adheren junctions
Interacts with actin
6
Q
Ig Superfamily
A
Ca2+ independent glycoproteins
Involved in recognition, binding or adhesion of cells
7
Q
Selectins
A
Ca2+ dependent glycoproteins
Bind to antigen on WBCs to cause rolling
8
Q
Integrins
A
Connect ECM to cytoskeleton, activate signaling pathways and interact with B cells
