WebBoth nonvisual arrestins were also found to self-associate 171–173 and even form heterodimers. 171,172 The mechanism of self-association of arrestin-1 and nonvisual subtypes appears to be different, as IP6 inhibits oligomerization of arrestin-1, while promoting self-association of nonvisual arrestins. 169,172 Two IP6 binding sites in … WebMutation of the IP6-binding sites impair oligomerization, reduce interaction with Mdm2, and inhibit p53-dependent antiproliferative effects of beta-arr2, whereas the competence for receptor regulation and signaling is maintained. These observations suggest that the intracellular concentration of beta-arr2 oligomers might...
