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. | |||||||
B2L11_HUMAN | LIG_Dynein_DLC8_1 | 50 | 56 | Phosphorylation of T56 by Mitogen-activated protein kinase 8 (MAPK8) in the Dynein-binding motif of Isoform Bim(L) of Bcl-2-like protein 11 (BCL2L11) inhibits binding to Dynein light chain 1, cytoplasmic (DYNLL1). Most Bim in healthy cells is sequestered away bound to light chain dynein molecules. Cells exposed to environmental stress up-regulate c-Jun NH(2)-terminal kinase (JNK) that phosphorylates both Bim and Bmf, releasing them from motor complexes and promoting apoptosis. | |||
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. | |||||||
B2L11_HUMAN | DEG_SCF_TRCP1_2 | 93 | 98 | Alternative splicing removes the extended SCF-TrCP degron motif of Bcl-2-like protein 11 (BCL2L11), abrogating binding to F-box/WD repeat-containing protein 1A (BTRC). Upon mitogen survival signals, RPS6KA1 and RPS6KA2 kinases are up-regulated and rapidly phosphorylate the three serines of Isoform Bim(EL) of Bcl-2-like protein 11 (BCL2L11). This facilitates the binding of betaTrCP and subsequent ubiquitination and degradation of Isoform Bim(EL) of Bcl-2-like protein 11 (BCL2L11). | |||
B2L11_HUMAN | LIG_Dynein_DLC8_1 | 110 | 116 | Alternative splicing removes the Dynein-binding motif of Bcl-2-like protein 11 (BCL2L11), abrogating binding to Dynein light chain 1, cytoplasmic (DYNLL1). Most BCL2L11 in healthy cells is sequestered away bound to DYNLL1 (the exception is Bim-S Isoform BCL2-like 11 transcript variant 9 of Bcl-2-like protein 11 (BCL2L11)). Cells exposed to environmental stress up-regulate c-Jun NH(2)-terminal kinases (JNK) that phosphorylate both BCL2L11 and BMF, releasing them from motor complexes and promoting apoptosis. |
