As with cryptochrome and phytochrome, the N-terminal photosensory region of the phototropins controls the activity of the C-terminal half of the protein, which contains a serine/threonine kinase domain. Following are some statements about photosensory region of the phototropins.
a) The activation of the C-terminal kinase domain then leads to receptor autophosphorylation on multiple serine residues that is required for all phototropin-mediated responses
b) In the dark, the N-terminal region, including the LOV domains, “cages” and inhibits the activity of the kinase domain
c) In the light, the N-terminal region, including the LOV domains, “cages” and inhibits the activity of the kinase domain
d) Absorption of blue photons by the LOV domains results in primary photochemical changes that lead to the uncaging of the kinase domain and its activation by the unfolding of the Jα-helix
Which one of the following combination of above statements is correct?
