DSCAML1 is a cell adhesion molecule that contains six Fibronectin type-III domains and ten Ig-like C2-type domains. DSCAML1 is involved in regulating isoneuronal self-avoidance, the tendency for sister arbors to avoid crossing each other and to spread out proportionately over an area. Isoneuronal self-avoidance is important for proper terminal branching (arborization). DSCAML1 also promotes heteroneuronal self-avoidance to maintain mosaic spacing between aII amacrine cells. DSCAML1 is expressed in liver, skeletal muscle, brain, kidney, pancreas and heart and exists as two isoforms produced by alternative splicing events.
Function:
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. Promotes both isoneuronal self-avoidance for creating an orderly neurite arborization in retinal rod bipolar cells and heteroneuronal self-avoidance to maintain mosaic spacing between AII amacrine cells.
Subcellular Location:
Cell membrane.
Tissue Specificity:
Detected in heart, liver, pancreas, skeletal muscle, kidney and in brain, in particular in the amygdala, caudate nucleus, corpus callosum, hippocampus, substantia nigra, thalamus and subthalamus.
Similarity:
Contains 6 fibronectin type-III domains.
Contains 10 Ig-like C2-type (immunoglobulin-like) domains.
