RACK1-GNB2L1 Background

RACK1 (guanine nucleotide binding protein (G protein), beta polypeptide 2-like 1), also known as GNB2L1, contains 7 WD repeats and belongs to the WD repeat G protein beta family. In the liver, RACK1 is expressed at higher levels in activated hepatic stellate cells than in hepatocytes or Kupffer cells. It is up-regulated in hepatocellular carcinomas and in the adjacent non-tumor liver tissue. RACK1 is involved in the recruitment, assembly and/or regulation of a variety of signaling molecules. It interacts with a wide variety of proteins and plays a role in many cellular processes. GNB2L1 binds to and stabilizes activated protein kinase C (PKC), increasing PKC-mediated phosphorylation. RACK1 may recruit activated PKC to the ribosome, leading to phosphorylation of EIF6. It inhibits the activity of SRC kinases including SRC, LCK and YES1. RACK1 also inhibits cell growth by prolonging the G0/G1 phase of the cell cycle. It enhances phosphorylation of BMAL1 by PRKCA and inhibits transcriptional activity of the BMAL1-CLOCK heterodimer.
