| Multiple low-affinity interactions give rise to high-avidity interactions that have increased binding strength, with more than additive affinity. | |||||||
| AMPH_HUMAN | LIG_Clathr_ClatBox_1 | 351 | 355 | Amphiphysin 1 contains two distinct motifs that bind to distinct sites on N-terminal beta-propeller domain of clathrin, resulting in increased binding strength to free domain. This, in combination with binding of its BAR domain to curved membranes, results in localisation of amphipysin to the periphery of the assembling clathrin lattice. The two clathrin-binding motifs are regulated by phosphorylation of adjacent modification sites (see switch details and switch details). | |||
| AMPH_HUMAN | LIG_Clathr_ClatBox_2 | 380 | 385 | Amphiphysin 1 contains two distinct motifs that bind to distinct sites on N-terminal beta-propeller domain of clathrin, resulting in increased binding strength to free domain. This, in combination with binding of its BAR domain to curved membranes, results in localisation of amphipysin to the periphery of the assembling clathrin lattice.

Type: Binary Subtype: Physicochemical compatibility | |||||||
| PTM of a residue in a motif or in its flanking regions alters the physicochemical and/or structural compatibility of the motif with its binding partner. This can either induce or enhance an interaction, or result in inhibition or even abrogation of an interaction. | |||||||
| AMPH_HUMAN | LIG_Clathr_ClatBox_1 | 351 | 355 | Phosphorylation of T350 adjacent to the clathrin-binding motif of Amphiphysin (AMPH) by CK2 subfamily inhibits binding to the Clathrin heavy chain 1 (CLTC). A second clathrin-binding motif in Amphiphysin (AMPH) is regulated in a similar manner (see switch details). Both these motifs cooperate in avidity-based binding to Clathrin heavy chain 1 (CLTC) (see switch details). | |||
