Anti-Dscam抗体(ab51974)

Cell adhesion molecule that plays a role in neuronal self-avoidance. Promotes repulsion between specific neuronal processes of either the same cell or the same subtype of cells. Mediates within retinal amacrine and ganglion cell subtypes both isoneuronal self-avoidance for creating an orderly dendritic arborization and heteroneuronal self-avoidance to maintain the mosaic spacing between amacrine and ganglion cell bodies. Receptor for netrin required for axon guidance independently of and in collaboration with the receptor DCC. In spinal chord development plays a role in guiding commissural axons projection and pathfinding across the ventral midline to reach the floor plate upon ligand binding. Enhances netrin-induced phosphorylation of PAK1 and FYN. Mediates intracellular signaling by stimulating the activation of MAPK8 and MAP kinase p38.

Primarily expressed in brain.

Contains 6 fibronectin type-III domains.
Contains 10 Ig-like C2-type (immunoglobulin-like) domains.

Ig-like C2-type domains 7 to 9 are sufficient for interaction with NTN1 and commissural axon outgrowth. The transmembrane domain is necessary for interaction with DCC.

Phosphorylated at tyrosine residues. Phosphorylation is enhanced by netrin.

Secreted and Cell membrane. Localized in the soma, cell membrane, axon and growth cone of dissociated commissural axons.
