Question

For tight junctions and adheren junctions select the correct properties or functions associated with it:

(A) Interacts with intermediate filaments at their cytoplasmic sides
(B) contains transmembrane proteins of the cadherin family
(C) Brings the plasma membrane of adjacent cells into such close apposition that even small molecules can’t leak between the cells.
(D) contains transmembrane proteins of the integrin family
(E) Shape and mechanical strength: contributor to the resistance of the whole epithelial sheet to stretching and tearing, and/or to its ability to change shape.
(F) Interacts with actin filaments on their cytoplasmic sides
(G) Signaling: recruits signaling molecules to its cytoplasmic side that convey information to the cell about its surroundings.
(H) Allows epithelia to maintain solute gradients between their apical and basal sides.
(I) Keeps the sheet anchored: mediates interaction of the cells with the basal lamina, or underlying extracellular matrix.
(J) Major source of adhesion between cells

Explanation / Answer

Tight junctions
(C) Brings the plasma membrane of adjacent cells into such close apposition that even small molecules can’t leak between the cells.
(H) Allows epithelia to maintain solute gradients between their apical and basal sides.


Adheren junctions
(A) Interacts with intermediate filaments at their cytoplasmic sides
(B) contains transmembrane proteins of the cadherin family
(E) Shape and mechanical strength: contributor to the resistance of the whole epithelial sheet to stretching and tearing, and/or to its ability to change shape.
(F) Interacts with actin filaments on their cytoplasmic sides


NOTE : Remaining others are properties of desmosomes and hemidesmosomes
