Study characterize the interaction of Keap1, a central antioxidant response regulator in Metazoa, with the replicative helicase subunit protein MCM3. Analysis suggests that structural determinants of the interaction of Keap1 with its critical downstream target - Nrf2 master transactivator of oxidative stress response genes - may have evolved in evolution to mimic the conserved helix-2-insert motif of MCM3.

Data report that MCM3 is a novel target of Pin1 through directly interacting with Pin1 WW domain. Proline-directed phosphorylation of MCM3 at S112 and T722 are crucial for the interaction with Pin1. MCM3 as a subunit of the MCM2-7 heterocomplex is part of the pre-replication complex responsible for replication licensing and is implicated in the formation of the replicative helicase during the replication progression.

Ki-67, MCM-3, and MCM-7, but not MCM-5 are reliable proliferative and diagnostic markers in discerning benign and malignant adrenocortical tumors.
-
this study shows that MCM3 is a novel proliferation marker in oral squamous cell carcinoma
-
High MCM3 expression is associated with bone metastasis and advanced human prostate cancer.
-
the decreased growth of osteosarcoma cells by MCM2 or MCM3 knockdown was reversed by DHX9 overexpression, indicating that MCM2 and MCM3 activity was DHX9-dependent.
-
reveal the Minichromosome Maintenance Complex to be a critical and directly regulated node within the miR-183 signaling network in MYCN-amplified neuroblastoma cells. Randomly selected MCMs 3 and 5 were experimentally confirmed as direct targets of miR-183.
-
The results of our preliminary study emphasize the need for future research on MCM-3 as a sensitive proliferation marker, providing an alternative to Ki-67, in cases of various major salivary gland epithelial tumors in children and adolescents.
-
These data establish new functions for KEAP1 within the nucleus and identify MCM3 as a novel substrate of the KEAP1-CUL3-RBX1 E3 ligase.
-
The aim of this study is to analyze the immunoexpression of Ki67, p53, MCM3 and PCNA markers in epithelial remnants of dental follicles of impacted teeth and to identify a possible correlation between the immunoexpression of these markers in dentigerous cysts and keratocystic odontogenic tumors.
-
High MCM-3 expression correlated with Cutaneous T-cell Lymphomas.
-
normal DNA replication and replication checkpoint activation is regulated through the novel phosphorylation of MCM3 by Chk1
-
Results show that in Glioma patients, MCM 2, MCM3 and MCM7 mRNA are up-regulated and correlated with poor outcome.
-
Of the total, the deregulation of several genes (CDK1, CDK2, CDK4, MCM2, MCM3, MCM4, EIF3a and RPN2) were potentially associated with disease development and progression.
-
Relatively lower MCM3 protein expression in follicular variant of papillary thyroid carcinoma comparing to classical type could be due to a different tumorigenic pathway favored in this type of tissue.
-
Expression of KB cell MCM3 was not affected by doxorubicin.
-
present study aimed to investigate the relationship between expression of minichromosome maintenance proteins (MCM-3, MCM-7), metallothioneins (MT-I/II, MT-III), and Ki-67 in 103 ovarian cancer cases, mostly of the serous histological type
-
Mcm2-7 loads onto origins during initiation as a double hexamer, yet does not act as a double-stranded DNA pump during elongation.
-
High MCM3 expression is associated with mucoepidermoid carcinomas and adenoid cystic carcinomas in salivary gland tumors.
