NLS-Cas12a Nuclease (MALS verified)

  • Synonym
    CRISPR-associated endonuclease Cas12a, CRISPR-associated endonuclease Cpf1, cas12a, Cpf1
  • Source
    NLS-Cas12a Nuclease (CAA-L5149) is expressed from E.coli cells. It contains AA Ser 2 - His 1228 (Accession # A0A5S8WF58).
    Predicted N-terminus: Met 1
  • Molecular Characterization
    Online(Ser 2 - His 1228) A0A5S8WF58

    This protein carries a polyhistidine tag at the N-terminus. The protein has a calculated MW of 147.6 kDa. The protein migrates as 130-140 kDa under reducing (R) condition (SDS-PAGE). This protein has two NLS, which leads to transport to the nucleus efficiently. It is ideal for in vitro and in vivo reactions.

  • Background
    Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-associated endonuclease from Lachnospiraceae bacterium,Cas12a, also known as Cpf1, is a 1200-1500 amino-acids long monomeric protein that belongs to the CRISPR/Cas system , an adaptive immune system of prokaryotes that has now become a powerful tool for genome editing. CRISPR/Cas12a belongs the class II (type 5) of the CRISPR/Cas system that is defined by a single-subunit effector. Cas12a has recently emerged as an alternative for Cas9, due to its distinct features such as the ability to target T-rich motifs, no need for trans-activating crRNA, inducing a staggered double-strand break and potential for both RNA processing and DNA nuclease activity. In addition, Cas12a is able to process more structured pre-CRISPR/RNA(crRNA) molecules into mature crRNAs which allows the possibility to use both mature or pre-crRNA for genome editing purposes. All these features make the CRISPR/Cas12a system a valuable genome-engineering tool. CRISPR-Cas12a has been successfully used to edit genomes in many mammalians cells and plants.
