Fig. 4From: Identification of a novel RHO heterozygous nonsense mutation in a Chinese family with autosomal dominant retinitis pigmentosaStructure model of rhodopsin-arrestin complex. Left: C-terminus of rhodopsin was shown in sticks, and the phosphorylation codes (D330, E332, T336, S338, E341) were highlighted. Arrestin was shown in vacuum electrostatics, blue area represents positive charge while red area represents negative charge. Normally, arrestin ‘reads’ phosphorylation codes of rhodopsin through code-sensing pockets. Right: K339X mutation of RHO produced a truncated protein and interfered the arrestin recruitmentBack to article page
