Scientific Data
Detection of Human L1CAM by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and human brain (motor cortex). PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human L1CAM Monoclonal Antibody (Catalog # MAB777) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for L1CAM at approximately 240 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.
Detection of Human L1CAM by Simple WesternTM. Simple Western lane view shows lysates of HeLa human cervical epithelial carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for L1CAM at approximately 337 kDa (as indicated) using 10 µg/mL of Mouse Anti-Human L1CAM Monoclonal Antibody (Catalog # MAB777). This experiment was conducted under reducing conditions and using the 66-440 kDa separation system.
Detection of Mouse L1CAM by Immunohistochemistry Analysis of L1 and pCK2 alpha immunofluorescence intensities rostral, central and caudal to the lesion site of the injured spinal cord at 6 weeks post-SCI in mice treated with trimebutine or honokiol. (A,C) Representative images of L1 (A) and pCK2 alpha (C) rostral (1 mm to the lesion center), central and caudal (1 mm to the lesion center) to the lesion site. (B,D) Quantitative analysis of L1 (B) and pCK2 alpha (D) immunoreactivities. *P<0.05, **P<0.01 versus the vehicle control; one-way ANOVA with Tukey's post hoc test; n=3 mice/group. HNK, honokiol; TMB, trimebutine; VC, vehicle control. Image collected and cropped by CiteAb from the following publication (https://pubmed.ncbi.nlm.nih.gov/28714852), licensed under a CC-BY license. Not internally tested by R&D Systems.
Detection of Mouse L1CAM by Western Blot Activation of L1-mediated intracellular signaling cascades in cultured mouse cerebellar granule cells treated with trimebutine. (A-E) Protein levels of L1 (A), phosphorylation levels of Akt1 (B) and Erk1/2 (C), protein levels of mTOR (D), and the ratio of Bcl-2/Bax levels (E) in cultured mouse cerebellar granule cells treated with trimebutine (TMB) at concentrations of 0, 5, 10 and 20 nM. *P<0.05, **P<0.01, ***P<0.001 versus the vehicle control; one-way ANOVA with Tukey's post hoc test; three independent experiments. Blots in C-E are from the same gel and therefore have the same beta -actin loading controls.

Background: L1CAM
L1CAM (Neural cell adhesion molecule L1, also known as L1, CD171 and NCAM-L1) is a 200-230 kDa member of the L1 family, Immunoglobulin (Ig) superfamily of molecules. L1 is recognized to play a key role in cell migration, adhesion, neurite outgrowth, myelination and neuronal differentiation. It does so through a series of cis and trans interactions that involve multiple copartners and target receptors. L1 is described as forming both homotypic and heterotypic complexes, the latter with molecules as diverse as the EGFR, NCAM, CD24, neurocan and various alpha v plus beta 1 and beta 3 integrins. Cells known to express L1 include immature oligodendrocytes, CD4+ T cells, B cells and monocytes, premyelinating Schwann cells, intestinal epithelial progenitor cells, and cerebellar granule plus Purkinje cells. Mature human L1 is a 1238 amino acid (aa) type I transmembrane protein. It contains an 1101 aa extracellular region (aa 20-1120) plus a 114 aa cytoplasmic domain (aa 1144-1257). The extracellular region possesses six C2-type Ig-like domains (aa 35-607) followed by five fibronectin (FN) type III repeats (aa 612-1108). The cytoplasmic tail contains no kinase motifs, but does possess a FIGQY peptide that interacts with ankyrin, and an RSLE sequence that mediates clathrin-associated endocytosis. At least five Ser residues are known to be phosphorylated. There are two splice variants, one each in the intracellular and extracellular domain. A deletion of RSLE (aa 1177-1180) adversely affects endocytosis, while a Leu substitution for aa 26-31 interfers with numerous heterotypic interactions. In general, the full-length L1 molecule is a neuron-associated isoform. L1 is known to undergo proteolysis, either by plasmin or ADAMs. This generates soluble isoforms of varying sizes (140-200 kDa) that retain bioactivity, and which can be incorporated into the surrounding ECM. The membrane fragments (30-80 kDa) undergo further processing, most importantly by gamma -secretase, to generate a soluble 28 kDa intracellular domain. This domain is SUMOylated, and believed to possess an NLS at Lys1147. Upon presumed entry into the nucleus, L1 is posited to activate L1-responsive genes. In the extracellular region, human and mouse L1 share 86% aa sequence identity.
