Question

Need help on questions 3 and 4, please. Drop-down answer choices are images.

Canine Scott Syndrome (CSS) is caused by a mutation in the splicing consensus motif in the TMEM16F gene. This mutation causes abnormal bleeding in the affected dogs.

iii) What does the mutation do to the TMEM16F protein? 

iv) What does the wild-type TMEM16F enzyme do that is required to stop bleeding? 

 

iv) What does the wild-type TMEM16F enzyme do that is required to stop bleeding?
switch phosphatidylserine from the internal leaflet to the external leaflet of the lipid bilayer in activated cells
switch phosphatidylserine from the external leaflet to the internal leaflet of the lipid bilayer in activated cells
switch phosphatidylcholine from the internal leaflet to the external leaflet of the lipid bilayer in activated cells
switch phosphatidylcholine from the internal leaflet of to the external leaflet of the lipid bilayer constitutively
switch phosphatidylserine from the internal leaflet to the external leaflet of the lipid bilayer constitutively
switch phosphatidylserine from the external leaflet to the internal leaflet of the lipid bilayer constitutively

iii) What does the mutation do to the TMEM16F protein?
splicing is unaffected, truncated protein that doesn't fold correctly and is degraded
splicing is affected, longer protein that retains normal enzymatic activity
splicing is unaffected, frameshift mutation, and truncated protein that is degraded
splicing is affected, frameshift mutation and protein is degraded
splicing is affected, frameshift mutation, protein that is secreted
splicing is affected, frameshift mutation, protein has more enzymatic activity
