Oligodendrocyte-myelin glycoprotein; also known as OMG and OMGP; is a cell membrane protein which contains eight LRR (leucine-rich) repeats. OMG / OMGP is a glycosylphosphatidylinositol-anchored protein expressed by neurons and oligodendrocytes in the central nervous system (CNS). OMG / OMGP is a cell adhesion molecule contributing to the interactive process required for myelination in the central nervous system. OMG / OMGP play roles in both the developing and adult central nervous system. OMG / OMGP participats in growth cone collapse and inhibition of neurite outgrowth through its interaction with NgR; the receptor for Nogo. This function requires its leucine-rich repeat domain; a highly conserved region in OMgp during mammal evolution. OMG / OMGP leucine-rich repeat domain is also implicated in the inhibition of cell proliferation. OMG / OMGP may also be involved in the formation and maintenance of myelin sheaths. Cell proliferation; neuronal sprouting and myelination are crucial processes involved in brain development and regeneration after injury.
Human OMGP/OMG Recombinant Protein (RPES4842)
Met 1-Pro 416
Measured by the ability of the immobilized protein to support the adhesion of C6 Rat brain glial cells. Immobilized OMG (0.8 µg/ml; 100 ?l/well) will mediate >15% C6 cell adhesion.
<1.0 EU per µg as determined by the LAL method.
A DNA sequence encoding the mature form of human OMGP (P23515-1) (Met 1-Pro 416) without the pro peptide was expressed; fused with a polyhistidine tag at the C-terminus.
> 97 % as determined by reducing SDS-PAGE.
