HuD (protein)

Introduction

HuD otherwise known as ELAV-like protein 4 is a protein that in humans is encoded by the ELAVL4 gene.[1][2]

The HuD/ELAVL4 protein is an RNA-binding protein.[3] HuD contains three RRM protein domains, enabling RNA binding.[4]

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.[5][6]

Interactions

Interactions

HuD (protein) has been shown to interact with NXF1.[7]
