Tyrobp encodes DAP12 (TYROBP), a transmembrane adaptor bearing an immunoreceptor tyrosine-based activation motif (ITAM) that couples multiple activating receptors in myeloid cells to intracellular signaling. In mouse microglia, macrophages, dendritic cells, and osteoclast lineage cells, DAP12 associates with receptors such as TREM2, SIRPβ1, and other Ig-like receptors to promote SYK-dependent cascades that regulate phagocytosis, cytokine production, chemotaxis, survival, and cytoskeletal remodeling. This signaling axis intersects with innate immune pathways including FcR-mediated responses and PI3K–AKT and MAPK signaling, shaping inflammatory tone and tissue surveillance. Altered TYROBP/DAP12 network activity is widely studied in contexts such as neuroinflammation and microglial state transitions, host defense, and bone remodeling disorders.
DAP12 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Tyrobp locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Tyrobp. 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 Tyrobp 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 Tyrobp-disrupted clones.
