WebQuestion: Hemidesmosomes are important for Answers A-D A rapid spread of small molecules between connected cells. с Blinking adjacent epithelial cells via cadherin molecules. C attaching epithelial cells to the basal lamina (basement membrane) Dinvagination or formation of tubes from epithelial sheets. WebThe LE domains have conserved disulfide bonds, which may be important for the tertiary structure of these domains [27,28]. The LN and LE domains form a short arm in the cross-shaped laminin-332 heterotrimer, and mediate binding to type VII collagen in hemidesmosomes, which are necessary for the stable association between the …
