Mouse OBCAM/OPCML Protein Product Information
Protein Construction:A DNA sequence encoding the mouse OPCML (NP_808574.2) (Ala5-Val313) was expressed with a C-terminal polyhistidine tag.
Expressed Host:Human Cells
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.
Mouse OBCAM/OPCML Protein QC Testing
Purity:> 95 % as determined by SDS-PAGE
Bio-Activity:1. Measured by its binding ability in a functional ELISA.
2. Immobilized mouse OPCmL-His at 10μg/mL (100μL/well) can bind human LSAMP-Fc (Cat:12136-H02H).
The EC50 of human LSAMP-Fc (Cat:12136-H02H) is 0.04-0.1 μg/mL.
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃

OBCAM/OPCML Background

Opioid-binding Cell Adhesion Molecule (OBCAM), also known as OPCML, is a GPI-anchored cell adhesion molecule in the plasma membrane. This neuron-specific protein, consists of three immunoglobulin (Ig)-like domains anchored to the membrane through a glycosylphosphatidylinositol (GPI)-tail. OPCML also belongs to the member of the IgLON family, a subgroup of the immunoglobulin superfamily, consisting of three members, LAMP, OBCAM, and Neurotrimin. These molecules interact homophilically and heterophilically within the family, and OBCAM acts only as heterodimers with LAMP or Neurotrimin and possibly inhibits neurite outgrowth from cerebellar granule cells. OBCAM has been presumed to play a role as a cell adhesion/recognition molecule. Furthermore, the OPCML protein defects may play an important role in the carcinogenesis of cervical or ovarian cancers, and this gene is regarded as a candidate TSG (tumor suppressor gene).
