Packet 6: Bonus 7

CELSR1 is an atypical one of these proteins, whose E-type binds to beta-catenin via their cytoplasmic tails. For 10 points each:
[10m] Name these type-1 transmembrane proteins that rely on a certain element for their function. These proteins’ desmosomal type include desmogleins (“DEZ-mo-gleens”), which are targeted in the autoimmune disease pemphigus vulgaris.
ANSWER: cadherins
[10e] Extracellular binding domains for this element allow cadherins to maintain cytoskeletal structure. This element’s divalent cation is stored in the sarcoplasmic reticulum.
ANSWER: calcium [or Ca; accept Ca2+ or divalent calcium]
[10h] Expression of E-cadherin and nectin-2-alpha leads to the recruitment of this complex to cell junctions in fibroblasts. This complex is responsible for regulating vesicle delivery.
ANSWER: sec6/8 complex [or exocyst]
