Welcome to ZOMEBase, the information center for the three PCI Zomes: COP9 Signalosome, the regulatory lid of the 26S proteasome and eIF3

What is a ZOME?

A "ZOME" is any one of three related multi-protein complexes:

the Cop9 Signalosome
the Regulatory Lid of the 26S proteasome
eIF3

These complexes were grouped together on the basis of similarities in their subunit composition and predicted structure. While subunits between the complexes share little primary sequence similarity, six subunits of all three complexes contain a PCI (Proteasome, CSN, eIF3) motif, while two subunits carry an MPN (Mpr1, Pad1, N-terminal) motif. This conserved six PCI / two MPN structure (among most higher eukaryotes) strongly suggests a common ancestor for these complexes. (1)

ZOMES, individually and in concert, affect proteome composition.

Genetic cell ablation.

Methods Mol Biol. 2014;1092:421-36

Abstract
Targeted cell ablation has proven to be a valuable approach to study in vivo cell functions during organogenesis, tissue homeostasis, and regeneration. Over the last two decades, various approaches have been developed to refine the control of cell ablation. In this review, we give an overview of the distinct genetic tools available for targeted cell ablation, with a particular emphasis on their respective specificity.
