CHN1Protein Product Information
Synonym:CHN1, ARHGAP2, CHN
Protein Construction:A DNA sequence encoding the human CHN1 (NP_001813.1) (Ala2-Phe459) was fused with two additional amino acids (Gly&Pro) at the N-terminus.
Expressed Host:Baculovirus-Insect Cells
Form & Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
CHN1Protein QC Testing
Purity:> 90 % as determined by SDS-PAGE
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method

1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
CHN1Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

CHN1, also known as chimerin 1, is a TPase-activating protein for ras-related p21-rac and a phorbol ester receptor. It is predominantly expressed in neurons, and plays an important role in neuronal signal-transduction mechanisms. CHN1 is involved in the assembly of neuronal locomotor circuits as a direct effector of EPHA4 in axon guidance. The CHN1 gene provides instructions for making two very similar proteins called α1-chimaerin and α2-chimaerin. These proteins play an important role in the early development of the nervous system. In particular, they help regulate complex chemical signaling pathways during the formation and development of nerve cells (neurons). These proteins help guide the growth of axons and dendrites, which are specialized extensions of neurons that transmit and receive nerve impulses throughout the nervous system.
