The protein encoded by this gene has amino acid sequence similarity to Csk tyrosine kinase and has the structural features of the CSK subfamily: SRC homology SH2 and SH3 domains, a catalytic domain, a unique N terminus, lack of myristylation signals, lack of a negative regulatory phosphorylation site, and lack of an autophosphorylation site. This protein is thought to play a significant role in the signal transduction of hematopoietic cells. It is able to phosphorylate and inactivate Src family kinases, and may play an inhibitory role in the control of T-cell proliferation. This protein might be involved in signaling in some cases of breast cancer. Three alternatively spliced transcript variants that encode different isoforms have been described for this gene.

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

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.
