**Background of Recombinant Human KCMF1 Protein**
Recombinant human KCMF1 (Killer Cell Modulatory Factor 1) protein is a biologically engineered form of the endogenous KCMF1. a ubiquitously expressed regulatory protein implicated in diverse cellular processes. KCMF1. also known as PARK20 or C19orf12. contains a conserved N-terminal plant homeodomain (PHD) and a C-terminal RING-finger domain, suggesting roles in protein-protein interactions and ubiquitination pathways. Studies highlight its involvement in modulating immune responses, particularly in natural killer (NK) cells and T cells, where it regulates cytotoxicity and cytokine production via MAPK signaling.
KCMF1 is also linked to cellular stress responses, including endoplasmic reticulum (ER) stress and autophagy. Its interaction with ubiquitin ligases, such as Parkin, associates it with neurodegenerative diseases like Parkinson’s disease, where loss-of-function mutations disrupt mitochondrial quality control. Additionally, aberrant KCMF1 expression has been observed in cancers, influencing tumor cell proliferation and apoptosis.
The recombinant form is typically produced in *E. coli* or mammalian expression systems, ensuring proper post-translational modifications for functional studies. Its applications span *in vitro* assays exploring immune regulation, neurodegeneration mechanisms, and cancer biology, as well as potential therapeutic development. Research on recombinant KCMF1 continues to unravel its multifaceted roles in health and disease, positioning it as a critical target for diagnostic and therapeutic innovation.
