Recombinant Human Zinc finger protein 703 (ZNF703)

Uniprot Id

Q9H7S9

Target Species

Human

Target Name

ZNF703

Target Full Name

Zinc finger protein 703

Target Function

Transcriptional corepressor which does not bind directly to DNA and may regulate transcription through recruitment of histone deacetylases to gene promoters. Regulates cell adhesion, migration and proliferation. May be required for segmental gene expression during hindbrain development.

Target Involvement

Luminal B breast cancers are the clinically more aggressive estrogen receptor-positive tumors. Amplification of a distal 8p12 locus occurs in around one third of the cases and ZNF703 is the single gene within the minimal amplicon. Amplification of the gene correlates with its protein expression in tumor cells. ZNF703 is a classical breast cancer oncogene since it is able to transform non-malignant cells and increase cellular proliferation.

Target Subcellular Location

Nucleus. Cytoplasm.

Target Protein Families

Elbow/Noc family

Target Tissue Specificity

Expressed in mammary epithelium.

Target Synonyms

FLJ14299; ZEPPO1; Zinc finger elbow-related proline domain protein 1; Zinc finger protein 703; ZN703_HUMAN; ZNF503L; znf703; ZPO1

Target Background

Predicted to enable DNA-binding transcription factor binding activity. Involved in several processes, including cellular response to estradiol stimulus; mammary gland epithelial cell differentiation; and positive regulation of mammary gland epithelial cell proliferation. Located in cytoplasm and nuclear matrix. Part of protein-containing complex.
