RNA-binding protein HuR regulates Rac1 nucleocytoplasmic shuttling through nucleophosmin in the intestinal epithelium.

Summary of "RNA-binding protein HuR regulates Rac1 nucleocytoplasmic shuttling through nucleophosmin in the intestinal epithelium."

The mammalian intestinal epithelium is a rapidly self-renewing tissue in the body, and its homeostasis is tightly regulated via well-controlled mechanisms. The RNA-binding protein HuR is essential for maintaining the gut epithelial integrity, and targeted deletion of HuR in intestinal epithelial cells (IECs) disrupts mucosal regeneration and delays repair after injury. Here, we defined the role of HuR in regulating subcellular distribution of small GTPase Rac1 and investigated the implication of nucleophosmin (NPM) as a molecular chaperone in this process.

Medical and Biotech [MESH] Definitions

A monomeric GTP-binding protein involved in nucleocytoplasmic transport of proteins into the nucleus and RNA into the cytoplasm. This enzyme was formerly listed as EC 3.6.1.47.

A rac GTP-binding protein involved in regulating actin filaments at the plasma membrane. It controls the development of filopodia and lamellipodia in cells and thereby influences cellular motility and adhesion. It is also involved in activation of NADPH OXIDASE. This enzyme was formerly listed as EC 3.6.1.47.

A basic leucine zipper transcription factor that regulates expression of MHC CLASS II GENES through its binding to a conserved X-box DNA sequence in the promoter region. It regulates the expression of genes involved in the UNFOLDED PROTEIN RESPONSE.

Y-box-binding protein 1 was originally identified as a DNA-binding protein that interacts with Y-box PROMOTER REGIONS of MHC CLASS II GENES. It is a highly conserved transcription factor that regulates expression of a wide variety of GENES.

A nucleocytoplasmic transport protein that binds to ALPHA KARYOPHERINS and RAN GTP BINDING PROTEIN inside the CELL NUCLEUS and participates in their export into CYTOPLASM. It is also associated with the regulation of APOPTOSIS and microtubule assembly.
