The antibody is generated against a synthetic peptide spanning amino acids 752–913 of human ZNF644, a region critical for its zinc finger domains . Specificity is validated via:
Western blot: Detects a single band at ~150 kDa in human cell lysates (HeLa, 293T) .
Immunoprecipitation: Confirms interaction with endogenous ZNF644 in 293T cells .
ZNF644 interacts with histone methyltransferases G9a/GLP to mediate H3K9 methylation, a hallmark of gene silencing. The FITC-conjugated antibody has been used to study this interaction in chromatin remodeling assays .
Elevated ZNF644 expression correlates with Graves' disease (GD) progression. The antibody aids in detecting ZNF644 in peripheral blood mononuclear cells (PBMCs), where it regulates circZNF644/miR-29a-3p/ICOS signaling in follicular helper T cells .
FITC conjugation enables fluorescence microscopy to confirm ZNF644’s cytoplasmic and nuclear localization, critical for its role as a ceRNA (competing endogenous RNA) .
