Description

General description

Disabled homolog 1 (UniProt: P97318; also known as DAB1) is encoded by the Dab1 gene (Gene ID: 13131) in murine species. Dab 1 is mainly expressed in the brain and serves as an adapter molecule involved in neural development where it is reported to direct the migration of cortical neurons past previously formed neurons to reach their proper layer. It is a cytosolic protein that is shown to be essential component of the reelin signaling pathway. It is shown to bind to the cytoplasmic tail of Reelin receptor, APO E receptor 2, and to LDL receptor. Dab1 can be phosphorylated on Tyr198, Tyr220, and Tyr232 upon reelin induction in embryonic neurons. It can also be phosphorylated on Ser524, but this phosphorylation is independent of reelin signaling. Tyrosine phosphorylation of Dab1 by Src family tyrosine kinases is considered to be the most critical downstream event in Reelin signaling. Dab1 contains a phosphotyrosine interaction domain (PID) (aa 36-189), which specifically binds to the Asn-Pro-Xaa-Tyr(P) motif found in many tyrosine-phosphorylated proteins. Seven different isoforms of Dab1 have been identified that are generated via alternative splicing. Clone 4H1 binds to an epitope within amino acids 281-460. (Ref.: Onoue, A., et al. (2014). Neurosci. Res. 88; 23-27).
