Names and origin

Protein names

Recommended name:
Regulatory protein zeste

Gene names

Name:

z

Organism

Drosophila virilis (Fruit fly)

Taxonomic identifier

7244 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Arthropoda › Hexapoda › Insecta › Pterygota › Neoptera › Endopterygota › Diptera › Brachycera › Muscomorpha › Ephydroidea › Drosophilidae › Drosophila

Protein attributes

Sequence length	618 AA.
Sequence status	Complete.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Involved in transvection phenomena (= synapsis-dependent gene expression), where the synaptic pairing of chromosomes carrying genes with which zeste interacts influences the expression of these genes. Zeste binds to DNA and stimulates transcription from a nearby promoter By similarity.
Subunit structure	Self-associates forming complexes of several hundred monomers By similarity.
Subcellular location	Nucleus By similarity.
