The human NDUFA1 gene codes for an essential component of complex I of the respiratory chain, which transfers electrons from NADH to ubiquinone. It has been noted that the N-terminal hydrophobic domain has the potential to be folded into an alpha-helix spanning the inner mitochondrial membrane with a C-terminal hydrophilic domain interacting with globular subunits of complex I. The highly conserved two-domain structure suggests that this feature is critical for the protein function and might act as an anchor for the NADH:ubiquinone oxidoreductase complex at the inner mitochondrial membrane. However, the NDUFA1 peptide is one of about 31 components of the 'hydrophobic protein' (HP) fraction of complex I which is involved in proton translocation. Thus the NDUFA1 peptide may also participate in that function. [provided by RefSeq, Jul 2008].

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.
