SERPINE1 mRNA-binding protein 1

UniProtKB accession:  Q9CY58

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Ribosome-binding protein that promotes ribosome hibernation, a process during which ribosomes are stabilized in an inactive state and preserved from proteasomal degradation (PubMed:34815424). Acts via its association with EEF2/eEF2 factor, sequestering EEF2/eEF2 at the A-site of the ribosome and promoting ribosome stabilization and storage in an inactive state (PubMed:34815424). May also play a role in the regulation of mRNA stability: binds to the 3'-most 134 nt of the SERPINE1/PAI1 mRNA, a region which confers cyclic nucleotide regulation of message decay (By similarity). Seems to play a role in PML-nuclear bodies formation (By similarity).
