DNA replication licensing factor MCM4 is a protein that in humans is encoded by the MCM4 gene.
The protein encoded by this gene is one of the highly conserved mini-chromosome maintenance proteins (MCM) that are essential for the initiation of eukaryotic genome replication. The hexameric protein complex formed by MCM proteins is a key component of the pre-replication complex (pre-RC) and may be involved in the formation of replication forks and in the recruitment of other DNA replication related proteins. The MCM complex consisting of this protein and MCM2, 6 and 7 proteins possesses DNA helicase activity, and may act as a DNA unwinding enzyme. The phosphorylation of this protein by CDC2 kinase reduces the DNA helicase activity and chromatin binding of the MCM complex. This gene is mapped to a region on the chromosome 8 head-to-head next to the PRKDC/DNA-PK, a DNA-activated protein kinase involved in the repair of DNA double-strand breaks. Alternatively spliced transcript variants encoding the same protein have been reported.
PABCO Transit, Inc., (now NJ Transit Morris, Inc.) doing business under the Morris County Metro brand, was a public transport company based in Dover, New Jersey operating local bus service in Morris County for New Jersey Transit. The company was originally called Passaic - Athena Bus Lines which operated service in Passaic and Clifton, New Jersey.
The Passaic-Athenia Bus Co. (originally Red Star Transportation up until 1922) operated the following routes prior to NJ Transit's takeover and contracting of the routes. The 702 was co-operated with Garfield & Passaic Transit as their #6 route and Community as its #1 route.
In October 2010, New Jersey Transit decided to take over these routes and split them into routes 871–875 and 880 by a newly created subsidiary called NJ Transit Morris, Inc. Morris County still subsidizes their operation. These routes are part of the Central Division.
On June 1, 2010 New Jersey Transit has decided to stop subsidizing the following routes leading to their discontinuation at the end of June.
