Spindlin 1 (SPIN1) sequesters ribosomal protein uL18 in the nucleolus, preventing it from interacting with c-mdm2 Proto-oncogene protein (MDM2), and alleviating uL18-mediated inhibition of MDM2 ubiquitin ligase activity toward p53 tumor suppressor protein (p53).

HDMX and HDM2 interact via their respective C-terminal RING domains but here we show that the presence of p53 induces an N-terminal interface under normal cellular conditions.
a novel uORF-based regulatory mechanism that is employed under conditions of hyperosmotic stress by at least two human mRNAs, coding for translation reinitiation/recycling factor eIF2D and E3 ubiquitin ligase MDM2. This novel mode of translational control selectively downregulates their expression and requires as few as one uORF.
MDM2 amplification in large-duct intrahepatic cholangiocarcinomas is more common than presently considered, and it may represent a unique biliary carcinogenetic process in which KRAS and TP53 mutations are less frequent.

results suggest overexpression of MDM2 is closely linked to inhibition of p53-dependent apoptosis of Theileria parva-infected lymphocytes; aberrant expression of host lymphocyte MDM2 induced by cytoplasmic existence of T. parva, directly and/or indirectly, is associated with aspects of this type of transformation of T. parva-infected lymphocytes
mutant Mdm2 was unable to rescue a p53-induced apoptotic phenotype.
Data indicate that knockdown of the Mdm2 and Mdm4 caused dramatic accumulation of mutant p53 protein.
Together with p53, provides an experimental model for characterizing drugs and genes that affect p53 signaling.

G protein-coupled receptor family C group 5 member A (GPRC5A) deficiency contributes to dysregulated proto-oncogene protein c-mdm2 (MDM2) via activated epidermal growth factor receptor (EGFR) signaling, which promotes lung tumor development.
MDM2 controls diabetic and non-diabetic renal antioxidant capacity via NRF2. NRF2 predominantly mediates MDM2's action on diabetic kidney disease. P53 is a key factor through which MDM2 activates NRF2 in diabetic kidney disease.
EmicroEBNA1 tumour cells are dependant upon Mdm2 for survival.
The proximal p53 inhibitor MDM2 is markedly downregulated in subcutaneous white and brown adipose tissues of mice during aging. Genetic disruption of MDM2 in adipocytes triggers canonical p53-mediated apoptotic and senescent programs, leading to age-dependent lipodystrophy and its associated metabolic disorders, including type 2 diabetes, nonalcoholic fatty liver disease, hyperlipidemia, and energy imbalance.
To investigate whether MDM2C462A, which retains p53 binding, has p53-suppressing activity, we generated Mdm2C462A/C462A;p53ER/- mice. Adult Mdm2-null mice died approximately 7 days after tamoxifen-induced p53 activation, indicating that in the absence of MDM2, MDMX cannot suppress p53. p53 activity is higher in the presence of MDM2C462A than in the absence of MDM2.

Mdm2 expression is required for cell survival even in the absence of p53. Moreover, results suggest that p73 compensates for loss of p53.
This gene is a target gene of the transcription factor tumor protein p53. The encoded protein is a nuclear phosphoprotein that binds and inhibits transactivation by tumor protein p53, as part of an autoregulatory negative feedback loop. Overexpression of this gene can result in excessive inactivation of tumor protein p53, diminishing its tumor suppressor function. This protein has E3 ubiquitin ligase activity, which targets tumor protein p53 for proteasomal degradation. This protein also affects the cell cycle, apoptosis, and tumorigenesis through interactions with other proteins, including retinoblastoma 1 and ribosomal protein L5. More than 40 different alternatively spliced transcript variants have been isolated from both tumor and normal tissues.
