Intracellular hyaluronan-binding protein 4

UniProtKB accession:  Q5XJA5

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:36653451). Acts via its association with eef2/eEF2 factor at the A-site of the ribosome, promoting ribosome stabilization in an inactive state compatible with storage (PubMed:36653451). Plays a key role in ribosome hibernation in the mature egg by promoting ribosome stabilization (PubMed:36653451). Ribosomes, which are produced in large quantities during oogenesis, are stored and translationally repressed in the egg and early embryo (PubMed:36653451).
