reach
"MIF-(50-65) and its variant bound to the MIF binding protein JAB1 and enhanced cellular levels of p27Kip1."

reach
"Furthermore, we found that downregulation of Jab1 induces the cell cycle arrest at G1 phase and upregulated the expression of p27, p53 and Bax gene."

reach
"Conversely, down-regulation of JAB1 by short interfering RNA substantially increased p27 expression and inhibited progression from G (1) to S phase of the cell cycle."

reach
"Jab1 negatively regulates expression of the cell cycle inhibitor cyclin dependent kinase inhibitor 1B (P27) through binding and targeting P27 for ubiquitination and degradation."

reach
"For example, SC deletion of nuclear Jun activation domain binding protein 1 (Jab1) impairs radial sorting by regulating the levels of p27Kip1, which in turn promotes SC exit from the cell cycle and differentiation."
