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. | |||||||
L1CAM_HUMAN | TRG_ENDOCYTIC_2 | 1176 | 1179 | Phosphorylation of Y1176 by Proto-oncogene tyrosine-protein kinase Src (SRC) in the endocytosis motif of Neural cell adhesion molecule L1 (L1CAM) inhibits binding to AP-2 complex subunit mu (AP2M1). | |||
L1CAM_HUMAN | TRG_ENDOCYTIC_2 | 1176 | 1179 | Phosphorylation of Y1176 in the endocytotic motif of Neural cell adhesion molecule L1 (L1CAM) by Proto-oncogene tyrosine-protein kinase Src (SRC) abolishes binding to the AP-2 complex subunit mu (AP2M1) and thereby inhibits internalisation of Neural cell adhesion molecule L1 (L1CAM). | |||
Type: Binary Subtype: Pre‑translational | |||||||
Pre-translational mechanisms such as alternative splicing, alternative promoter-usage and/or RNA editing result in inclusion or removal of exons that contain an entire or partial motif. | |||||||
L1CAM_HUMAN | TRG_ENDOCYTIC_2 | 1176 | 1179 | Alternative splicing removes the endocytosis motif of Neural cell adhesion molecule L1 (L1CAM), abrogating binding to AP-2 complex subunit mu (AP2M1). This motif is required for sorting of L1CAM to the axonal growth cone of neurons and its clathrin-mediated internalisation. Non-neuronal cells, such as Schwann cells, do not require these motifs, probably because these cells are not highly polarised. | |||
Type: Binary Subtype: Allostery | |||||||
The binding properties of a motif or a motif-binding domain are modulated indirectly by allosteric effects resulting from PTM or effector binding at a site that is distinct from the actual interaction interface. | |||||||
L1CAM_HUMAN | TRG_ENDOCYTIC_2 | 1176 | 1179 | Binding of 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate to the AP-2 complex alpha, beta and mu subunits exposes a binding site on the AP-2 complex subunit mu (AP2M1) subunit for recruitment of Neural cell adhesion molecule L1 (L1CAM) via an endocytosis motif. |
