Integrin (location, how does it bind to what)
Cell-membrane anchored protein (transmembrane protein), binds with extracellular matrix (non-covalent and reversible)and with the actin cytoskeleton in the cell
Thight junctions "occluding junctions" (location, function, structure)
Located within the epithelia (between epithelial cells, seal adjacent epithelial cells and prevent molecule and ions to pass, cell membranes are connected by transmembrane proteins (protein strands)
Desmosomes (location, function, structure)
interact with each other in intercellular matrix, act like rivets and keep cells together, keratin fibres (interact with intracellular matrix) and partially embedded proteins
Gap juctions (location, function, structure)
span between to adjacent cell membranes, let water and small dissolved molecule pass ,specialised protein channels (connexins) composed of 5 subunits,
Plasmodesmata (structure, function)
Consists of pores or channels between plant cells, create gaps that connect plant cells, allows molecules and substances to move between adjacent cells, desmotubule (ER that links cells together)
Apical membrane (position, suiting junctions)
Surface of the plasma membrane that faces towards the lumen, tight junctions seal adjacent epithelial cells underneath the apical surface
Basolateral surface (position, suiting junction)
oriented away from the lumen (cell membrane)
Basement membrane (position, suiting junction)$
attached to underlying tissue, ???
