MERTK encodes the receptor tyrosine kinase MerTK, a TAM family member that regulates efferocytosis and immune homeostasis by recognizing phosphatidylserine via bridging ligands such as GAS6 and PROS1. MerTK activation triggers downstream PI3K–AKT, MAPK/ERK, and STAT signaling, shaping macrophage and microglial clearance programs, limiting inflammatory cytokine output, and supporting tissue remodeling. In cancer biology, aberrant MerTK signaling has been linked to tumor cell survival, invasiveness, and immune evasion within the tumor microenvironment. In the nervous system and retina, MerTK-dependent phagocytosis is relevant to debris clearance and inflammatory regulation, providing a framework to study disease-associated dysregulation of innate immune pathways.
MerTK Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MERTK locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MERTK. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt MERTK function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of MERTK-disrupted clones.
