The protein encoded by this gene is a member of the diaphanous-related formins (DRF), and contains multiple domains, including GBD (GTPase-binding domain), DID (diaphanous inhibitory domain), FH1 (formin homology 1), FH2 (formin homology 2), and DAD (diaphanous auto-regulatory domain) domains. This protein is thought to play a role in actin filament polymerization in cardiomyocytes. Mutations in this gene have been associated with dilated cardiomyopathy (DCM), characterized by dilation of the ventricular chamber, leading to impairment of systolic pump function and subsequent heart failure. Increased levels of the protein encoded by this gene have been observed in individuals with hypertrophic cardiomyopathy (HCM). Alternative splicing results in multiple transcript variants encoding different isoforms. A muscle-specific isoform has been shown to possess a casein kinase 2 (CK2) phosphorylation site at the C-terminal end of the FH2 domain. Phosphorylation of this site alters its interaction with sequestosome 1 (SQSTM1), and targets this isoform to myofibrils, while other isoforms form cytoplasmic aggregates.

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.
