NDE1 and NDEL1: Multimerisation, alternate splicing and DISC1 interaction
Bradshaw NJ., Christie S., Soares DC., Carlyle BC., Porteous DJ., Millar JK.
Nuclear Distribution Factor E Homolog 1 (NDE1) and NDE-Like 1 (NDEL1) are highly homologous mammalian proteins. However, whereas NDEL1 is well studied, there is remarkably little known about NDE1. We demonstrate the presence of multiple isoforms of both NDE1 and NDEL1 in the brain, showing that NDE1 binds directly to multiple isoforms of Disrupted in Schizophrenia 1 (DISC1), and to itself. We also show that NDE1 can complex with NDEL1. Together these results predict a high degree of complexity of DISC1-mediated regulation of neuronal activity. © 2008 Elsevier Ireland Ltd.
