CHD1

PF3D7_1023900 (CHD1) is a putative chromodomain-helicase-DNA-binding protein of P. falciparum identified as a binding partner of the chromatin-associated protein PfMORC (PF3D7_1468100) by co-immunoprecipitation/mass spectrometry, placing it within a nuclear complex that modulates epigenetic control of gene expression during asexual blood stage development (PMID:39412522). Beyond this complex membership, no direct enzymatic activity, substrate, localization, or independent functional role has been characterized for CHD1 itself in the available corpus.

   To position CHD1 within P. falciparum chromatin biology, its physical association with the PfMORC complex was established, connecting an otherwise uncharacterized putative chromatin remodeler to a defined epigenetic regulatory machinery.

   Open questions at the time

   • Single Co-IP/MS without reciprocal validation from a CHD1 tag
   • No direct enzymatic (helicase/remodeling) activity demonstrated for CHD1
   • No genetic or functional assay defining CHD1's independent role or contribution to the complex

• Whether CHD1 has intrinsic chromatin-remodeling activity, what genes or genomic loci it acts on, and whether it is functionally required within the PfMORC complex remain unresolved.
• No demonstrated catalytic activity for CHD1
• No knockdown/knockout phenotype for CHD1
• No subcellular localization data specific to CHD1
