Switches

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

SWTI000160:

Dual phosphorylation of S349 and S353 in the TrCP1-binding motif of Prolactin receptor (PRLR) targets the protein to the SCF ubiquitin ligase complex, which marks it for degradation.
SWTI000625:

Alternative Splicing removes the degron motif of Prolactin receptor (PRLR) abrogating binding to F-box/WD repeat-containing protein 11 (FBXW11). SCF-beta-TrCP2 negatively regulates the long isoform of PRLR (Isoform 1). Should be noted that TrCP2 has a predominately cytoplasmic localisation compared to TrCP1 that is located in the nucleus. The mechanism for the down-regulation of the intermediate (Isoform Intermediate) and short (Isoform Short form 1a and Isoform Short form 1b) that lack the TrCP degron is still not known. However it should be noted that the short and intermediate are either partially deficient or entirely deficient in mediating the signal transduction pathways induced by PRL (see Kine et al. (1999) (here) and Ross et al. (1997) (here)). This though is likely due to the missing STAT5-SH2-binding motif.
