LRRTM2 Protein, Human, Recombinant (His Tag)

• Background:

  LRRTM2 (Leucine-Rich Repeat Transmembrane Neuronal 2) is a Protein Coding gene. LRRTM2 belongs to the LRRTM family and is a key regulator of excitatory synapse development and function. It localizes to excitatory synapses in transfected hippocampal neurons, and shRNA-mediated knockdown of LRRTM2 leads to a decrease in excitatory synapses without affecting inhibitory synapses. LRRTM2 interacts with PSD-95 and regulates surface expression of AMPA receptors, and lentivirus-mediated knockdown of LRRTM2 in vivo decreases the strength of evoked excitatory synaptic currents. LRRTM2 induces only excitatory synapses, and that it also acts to induce synapses in transfected neurons similarly to neuroligin-1. Diseases associated with LRRTM2 include Tarp Syndrome and Histrionic Personality Disorder.

• Gene Name:

  Leucine rich repeat transmembrane neuronal 2

• Expression System:

  HEK293 Cells

• Tag:

  C-His

• Endotoxin:

  < 1.0 EU per μg protein as determined by the LAL method.

• Purity:

  > 95 % as determined by SDS-PAGE.

• Activity:

  At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

• Form:

  Lyophilized

• Buffer:

  Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

• Molecular Weight:

  The recombinant human LRRTM2 consists of 400 amino acids and predicts a molecular mass of 46 kDa.

• Storage Conditions:

  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. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
