AlkB Homolog 4, Lysine Demethylase (ALKBH4) Antibody

Background

ALKBH4 is a nuclear enzyme that functions as a lysine demethylase, specifically targeting methylated lysine residues on non-histone proteins. ALKBH4 plays a critical role in cytoskeletal dynamics, particularly by demethylating actin, which regulates actin filament assembly and cellular motility. Its activity ensures proper cytokinesis, cell shape maintenance, and migration during mitosis and development. ALKBH4 also participates in DNA repair and gene regulation by interacting with other proteins involved in chromatin remodeling and transcription. Dysregulation of ALKBH4 is linked to defects in cell division, genomic instability, and impaired cellular motility, contributing to developmental abnormalities and cancer progression. In cancer biology, ALKBH4’s regulation of cytoskeletal dynamics has been shown to promote cancer cell invasion and metastasis. Its role in demethylating non-histone proteins distinguishes ALKBH4 from other ALKB family members, highlighting its importance in post-translational modification and cellular homeostasis.
