MMP15 Knockout HAP1 Cell Line

The choice depends on whether you are studying MMP15 (MT2-MMP)'s role as a transmembrane membrane-type matrix metalloproteinase or its functions in vascular biology and pro-MMP-2 activation. The Knockout line is the standard tool for asking whether MMP15 is required for these processes — MMP15 is a type I transmembrane MT-MMP that, together with MMP14 (MT1-MMP), activates pro-MMP-2 at the cell surface and degrades ECM substrates. Overexpression is useful for studying MMP15 in heterologous expression contexts. For matrix metalloproteinase research, the EDITGENE MMP15 Knockout in HAP1 enables study of MT2-MMP biology. MMP14 (MT1-MMP) is the dominant pro-MMP-2 activator — MMP15's contribution is typically secondary. MMP15 has been implicated in cardiovascular development and angiogenesis. Rescue with wild-type or catalytically-dead MMP15 is the standard specificity control. This product complements parallel MMP16 and MMP25 Knockouts in HAP1 for MT-MMP family dissection.

Primary applications: • pro-MMP-2 activation: zymography or MMP-2 activity assays to characterize MMP15's contribution to MMP-2 maturation. • Vascular biology studies: in heterologous endothelial-relevant contexts, MMP15's role in angiogenesis and vascular development. • ECM degradation: substrate degradation analysis with collagen, fibronectin, and other MMP15 substrates. • MT-MMP family functional dissection: parallel analysis with MMP14 (in published systems), MMP16, MMP25 for paralog-specific characterization. EDITGENE recommends this model for researchers investigating MT2-MMP biology and MT-MMP family-mediated ECM remodeling.

Yes. MMP15 rescue experiments require attention to membrane topology: • Construct design: use a codon-modified MMP15 sequence with a small intracellular C-terminal tag (FLAG, HA). MMP15 has the typical MT-MMP transmembrane architecture — preserve all elements including the cytoplasmic tail (regulatory phosphorylation sites). • Catalytically-dead rescue: HEXXH motif glutamate mutation (E to A) abolishes metalloprotease activity. • Furin processing: active MMP15 is generated by furin cleavage of the prodomain — confirm mature form in rescue cells. • Functional readout: rescue should restore pro-MMP-2 activation and ECM substrate degradation patterns. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.
