The Drosophila neural receptor Dscam1 (Down syndrome cell adhesion molecule 1) plays an essential role in neuronal wiring and self-avoidance. Dscam1 potentially encodes 19,008 ectodomains through alternative RNA splicing and exhibits exquisite isoform-specific homophilic binding, which makes it an exceptional example for studying protein binding(More)
Down syndrome cell adhesion molecule 1 (Dscam1), a member of the immunoglobulin (Ig) superfamily, plays important roles in both the nervous and the immune systems. Via alternative RNA splicing, Drosophila Dscam1 encodes a vast family of Ig-containing proteins that exhibit isoform-specific homophilic binding. Whether different Dscam1 isoforms adopt the same(More)
Drosophila Down syndrome cell adhesion molecule 1 (Dscam1) plays a critical role in neural development. It can potentially form 38 016 isoforms through alternative RNA splicing, and exhibits isoform-specific homophilic interaction through three variable Ig domains (Ig2, Ig3 and Ig7). The diversity and homophilic interaction are essential for its functions.(More)
