Absorption of a photon of light by rhodopsin triggers mechanisms responsible for excitation as well as regulation of the phototransduction cascade. Arrestins are a family of proteins that appear to be responsible for terminating the active state of G-protein-coupled receptors. One of the major substrates of light-dependent phosphorylation in the visual(More)

Recently, a set of nine nonmagic nuclei with anomalous values of the B(E2) ratio B 4/2 ≡ B(E2; 4 + 1 → 2 + 1)/B(E2; 2 + 1 → 0 + 1) < 1 were identified. Such values are outside the range allowed by current collective models. In the present work, the B(E2; 4 + 1 → 2 + 1) values for two of these nuclei, 98 Ru and 180 Pt, were re-measured to determine if the(More)
