ProteinMotifStartEndSwitch descriptionInformation

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.
HSF4_HUMANMOD_SUMO292295The phosphorylation-dependent sumoylation of the PDSM (phosphorylation-dependent sumoylation motif) strongly represses Isoform HSF4B of Heat shock factor protein 4 (HSF4) activity.
details
ESR2_HUMANMOD_SUMO_PHOS47The GSK3-beta binding site at S12 in Estrogen receptor beta (ESR2) is primed by (most likely) RAC-alpha serine/threonine-protein kinase (AKT1). This enhances the binding of SUMO-conjugating enzyme UBC9 (UBE2I) at the adjacent Sumoylation site. This site is also primed at S6 (most likely) by AKT1. The addition of SUMO at K4 stabilises ESR2 as it prevents the ubiquitination at K4 (see switch details)
details
ESR2_HUMANMOD_SUMO_PHOS47Sumoylation of K4 in Estrogen receptor beta (ESR2) is inhibited by ubiquitination K4. This destabilises ESR2 increasing its turnover (see also switch details)

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.
HSF4_HUMANMOD_SUMO292295Alternative splicing removes the sumoylation motif of Heat shock factor protein 4 (HSF4), abrogating binding to SUMO-conjugating enzyme UBC9 (UBE2I). The phosphorylation-dependent sumoylation of the PDSM (phosphorylation-dependent sumoylation motif) strongly represses Isoform HSF4B of Heat shock factor protein 4 (HSF4) activity.
details
PML_HUMANMOD_SUMO489492Alternative splicing removes the SUMO motif of Protein PML (PML), abrogating binding to SUMO-conjugating enzyme UBC9 (UBE2I). The study identified a major sumoylation site within the nuclear localisation signal (NLS) of PML. Although they did not determine whether the lysine residue regulates the NLS, they found that sumoylation was not necessary for nuclear localisation and that SUMO-modification only occurs in the nucleus.

NFAC1_HUMANMOD_SUMO701704Alternative splicing removes the Sumoylation motif (SIM) of Nuclear factor of activated T-cells, cytoplasmic 1 (NFATC1), preventing the sumolyation of Isoform A-alpha of Nuclear factor of activated T-cells, cytoplasmic 1 (NFATC1). Both the Isoform C-alpha of Nuclear factor of activated T-cells, cytoplasmic 1 (NFATC1) and Isoform A-alpha of Nuclear factor of activated T-cells, cytoplasmic 1 (NFATC1) exert a differential effect upon IL-2 expression. However, the longer isoform, Isoform C-alpha of Nuclear factor of activated T-cells, cytoplasmic 1 (NFATC1), has a sumoylation motif and is therefore negatively regulated in a sumolyation-dependent manner.

Switches that have unique regulatory mechanisms. As more instances accumulate these switches may be worthy of a novel switch type
PML_HUMANMOD_SUMO159162Sumoylation of K160 induces binding to the Protein PML (PML) protein. SUMO-modified forms of PML are essential for the recruitment of Protein PML (PML) to PML nuclear bodies.

PML_HUMANMOD_SUMO159162Sumoylation of K160 induces binding to the Protein PML (PML) protein. SUMO-modified forms of PML are essential for the recruitment of Death domain-associated protein 6 (DAXX) to PML nuclear bodies.
