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. | |||||||
SIG12_MOUSE | LIG_TYR_ITIM | 430 | 435 | Alternative splicing removes the ITIM (immunoreceptor tyrosine-based inhibitory motif) of Sialic acid-binding Ig-like lectin 12 (Siglec12), abrogating binding to Tyrosine-protein phosphatase non-receptor type 11 (Ptpn11). | |||

Type: Specificity Subtype: Altered binding specificity | |||||||
The balance of the competition for overlapping or adjacent, mutually exclusive interaction interfaces is tipped in favor of one of the interactors by PTM-dependent modulation of the intrinsic affinity of a binding region. Multiple, successive PTMs allow sequential switching of different binding partners in an ordered manner by step-wise alteration of binding specificity. | |||||||
CTLA4_MOUSE | LIG_SH2_STAT5 | 201 | 204 | Dephosphorylation of Y201 of Cytotoxic T-lymphocyte protein 4 (Ctla4) switches the specificity of Ctla4 from SH2 domain-containing proteins like Tyrosine-protein phosphatase non-receptor type 11 (Ptpn11) to the AP-2 complex mu subunit (AP-2 complex subunit mu (Ap2m1)), thereby switching from inhibitory signal transmission and negative regulation of T cell responses to internalization and inactivation of Ctla4. |
