hud

HuD otherwise known as ELAV-like protein 4 is a protein that in humans is encoded by the ELAVL4 gene.
The HuD/ELAVL4 protein is an RNA-binding protein. HuD contains three RRM protein domains, enabling RNA binding.
HuD is expressed only in neurons and it binds to AU-rich element-containing mRNAs. As a result of this interaction the half-life of the transcript is increased. HuD is important in neurons during brain development and plasticity.
