Growth arrest and DNA-damage-inducible, gamma interacting protein 1
Gene Summary
GADD45GIP1 acts as a negative regulator of G1 to S cell cycle phase progression by inhibiting cyclin-dependent kinases. Inhibitory effects are additive with GADD45 proteins but occurs also in the absence of GADD45 proteins. GADD45GIP1 acts as a repressor of the orphan nuclear receptor NR4A1 by inhibiting AB domain-mediated transcriptional activity. GADD45GIP1 may be involved in the hormone-mediated regulation of NR4A1 transcriptional activity.
