Scientific Data Images for Human DSCAM Long Isoform Antibody

Detection of Recombinant Human DSCAM antibody by Western Blot.

Detection of Recombinant Human DSCAM by Western Blot.

Western blot shows 25 ng of Recombinant Human DSCAM (Catalog # 3666-DS) and Recombinant Human DSCAM-L1 (Catalog # 3315-DL). PVDF Membrane was probed with 1 µg/mL of Mouse Anti-Human DSCAM Long Isoform Monoclonal Antibody (Catalog # MAB36661) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for DSCAM at approximately 250 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.
DSCAM antibody in A172 Human Cell Line by Immunocytochemistry (ICC).

DSCAM in A172 Human Cell Line.

DSCAM was detected in immersion fixed A172 human glioblastoma cell line using Mouse Anti-Human DSCAM Long Isoform Monoclonal Antibody (Catalog # MAB36661) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (orange; Catalog # NL007) and counter-stained with DAPI (blue).

Detection of Mouse Human DSCAM Long Isoform Antibody by Western Blot

The C-terminus of DSCAM is not required for protein stability or localization. (C) Western blots of DSCAM protein immunoprecipitated from neonatal brains showed no change in the size or amount of DSCAM in Dscam∆C/∆C mutants. The antibody specificity is confirmed by the lack of signal from Dscam-/- brains.

Background: DSCAM

Down syndrome cell adhesion molecule (DSCAM) is a 220 kDa type I transmembrane glycoprotein and member of the immunoglobulin superfamily (1). Human DSCAM, which maps to a Down syndrome region of chromosome 21q22.2‑22.3, is synthesized as a 2012 amino acid (aa) precursor that contains a 17 aa signal sequence, a 1578 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 396 aa cytoplasmic tail. The ECD contains ten Ig-like C2-type domains, six fibronectin type III domains, and 16 potential sites for N-linked glycosylation. Splicing variants lead to a second, shorter isoform, which has a ten aa substitution for aa 1562‑1571 in the longer isoform, and a deletion of residues corresponding to aa 1572‑2012 in the longer isoform. Human mature DSCAM is 98% aa identical to mature mouse and rat DSCAM. Studies on mice have shown that DSCAM is expressed widely in the developing nervous system (1, 2). More recent studies indicate that DSCAM plays an important role in neurite arborization, cell body spacing, and lamina-specific synaptic targeting in vertebrate retina (2‑4). DSCAM directly binds to cytoplasmic Pak1 and stimulates Pak1 phosphorylation and activity (5). In addition, DSCAM activates both JNK and p38 MAP kinases, and expression of the cytoplasmic domain of DSCAM induces a morphological change in cultured cells that is JNK-dependent (5). Thus, it appears that DSCAM signals through Pak1 and functions in axon guidance. Furthermore, DSCAM, in collaboration with DCC, interacts with Netrin-1 and is a receptor required for Netrin-dependent commissural axon outgrowth and pathfinding (2, 6).
