ACVR1 encodes activin A receptor type I (ACTR-I/ALK2), a serine/threonine kinase receptor in the TGF-β superfamily that transduces BMP ligand signals to SMAD1/5/8 and downstream transcriptional programs. In human cells, ACTR-I participates in regulation of osteogenic and chondrogenic differentiation, tissue patterning, and cell fate decisions through canonical BMP–SMAD signaling and crosstalk with MAPK and other developmental pathways. Dysregulated ACVR1 activity perturbs BMP signaling dynamics and is implicated in disorders of ectopic ossification and skeletal development, including fibrodysplasia ossificans progressiva. ACVR1 is also used as a pathway node to study BMP receptor complex assembly, signal amplitude control, and context-dependent transcriptional outputs.
ACTR-I Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ACVR1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ACVR1. 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 ACVR1 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 ACVR1-disrupted clones.
