ERG, ETS transcription factor

Alias

erg-3 | p55

This gene encodes a member of the erythroblast transformation-specific (ETS) family of transcriptions factors. All members of this family are key regulators of embryonic development, cell proliferation, differentiation, angiogenesis, inflammation, and apoptosis. The protein encoded by this gene is mainly expressed in the nucleus. It contains an ETS DNA-binding domain and a PNT (pointed) domain which is implicated in the self-association of chimeric oncoproteins. This protein is required for platelet adhesion to the subendothelium, inducing vascular cell remodeling. It also regulates hematopoesis, and the differentiation and maturation of megakaryocytic cells. This gene is involved in chromosomal translocations, resulting in different fusion gene products, such as TMPSSR2-ERG and NDRG1-ERG in prostate cancer, EWS-ERG in Ewing's sarcoma and FUS-ERG in acute myeloid leukemia. More than two dozens of transcript variants generated from combinatorial usage of three alternative promoters and multiple alternative splicing events have been reported, but the full-length nature of many of these variants has not been determined.

Advantages of HAP1 knockout cell lines

Easily characterize knockout of your gene-of-interest in a biological context
Ready-made knockout cell lines are available for all non-essential human genes
Editing has been confirmed by Sanger sequencing of genomic DNA
Two independent knockout products for each gene, allowing second-clone analysis if more than one data point is required

Proven models

Our catalog of cell lines has become a gold-standard resource in antibody validation, cancer research, and early drug-discovery research. Horizon was recently recognized by CiteAb as the Cell Line Supplier to Watch in Cancer Research for 2024. Read more about the CiteAb award.

Why are HAP1 cells an ideal option for gene-edited cell line models?

Our HAP1 cell line database represents the synergy of two great systems - the amenability of human haploid HAP1s to gene editing and CRISPR-Cas9 technology. HAP1 is a human near-haploid cell line derived from the chronic myelogenous leukemia (CML) cell line KBM-7. KBM-7 cells were derived from a male patient and lack a Y chromosome. Therefore, haploid HAP1 cells contain a single X chromosome. For more details on how the HAP1 cell line was created and their full genotype, please see the references tab.

HAP1 cell line properties include:

Sustained growth at single cell dilutions
Ease of transfection
Rapid doubling time
Not selected for ploidy status

Will have haploid and diploid populations

The majority of commonly used cell lines are diploid or even have more than two copies of any particular allele. When gene editing for loss of function mutations, each allele has to be modified for the phenotype to be expressed. The HAP1 cell line has the advantage of having one copy of each gene meaning you can be sure the edited allele will not be masked by addition alleles. With passaging, HAP1 cells will spontaneously diploidize over time. However, the knockout will not be affected by diploidization as it is a duplication of the edited allele that gives rise to the diploid state.

See our HAP1 publication list to see how the cell line has been applied for a wide range of biological processes and assays, such as DNA damage repair pathway, stress responses, disease modeling as well as antibody validation.
