Switches

This ELM instance is part of the following 2 switching mechanisms annotated at the switches.ELM resource:

SWTI000107:

Phosphorylation of S775 by RAC-alpha serine/threonine-protein kinase (AKT1) in the 14-3-3-binding motif of Ataxin-1 (ATXN1) induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein.
SWTI000291:

Phosphorylation of S775 switches binding specificity of Ataxin-1 (ATXN1) from the splicing factor Splicing factor U2AF 65 kDa subunit (U2AF2) to 14-3-3 proteins (e.g. 14-3-3 protein zeta/delta (YWHAZ)). While association with the spliceosome protects ATXN1 from self-association, its phosphorylation-dependent recruitment to 14-3-3 proteins (e.g. YWHAZ) might result in aggregation.
