Card Set Information
difference between hemidesmosomes and focal adhesions vs. tight junctions, desmosomes, adheren junctions, and gap junctions
Hemi and focal are cell-matrix adhesion
TJ, AJ, GJ, and desmosomes are cell-cell adhesion
Difference between Hemi adn FA vs. AJ and desmosomes.
hemi and focal adhesions are made of integrins
desmosomes and adheren junctions are made of cadherins
difference between adheren junctions and gap junctions?
AJs are actin filaments
gap junctions are intermediate filaments
(i think desmosomes are too)
Because the binding of lectins to their specific sugar ligand requires extracellular Ca2+, they are called __.
What do detergents in terms of their ends?
the nonpolar ends of the detergent molecules associate with the nonpolar residues of hte protein tha thad previously been in contact with the fatty acid chains
the polar ends interact with the surrounding water molecules, keeping the protein in solution
What kind of domains do selectins have?
EGF- like domain
structural domain, which can be repeat domains of different kinds
What are the IG-like domains bound by?
What do calcium ions do in cadherins?
are situated between the successive domains of the cadherin where they play a critical role in maintaining the rigidity of the extracellular portion of hte protein
What do adherens and tight junctions do that desmosomes and gap junctions dont?
adherens and tight junctions encircle the cell
gap junctions adn desmosomes do not
