Mutations in the Tar DNA binding protein of 43 kDa (TDP-43; TARDBP) are associated with amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with TDP-43(+) inclusions (FTLD-TDP). To determine the physiological function of TDP-43, we knocked out zebrafish Tardbp and its paralogue Tardbp (TAR DNA binding protein-like), which lacks the(More)
For the analysis of Ca(2+)-dependent signaling, acetoxymethyl (AM)-derivatized ion indicators have become a popular tool. These indicators permeate membranes in an ion-insensitive form but, within cells, esterases hydrolyze these compounds to release ion-sensitive dyes. However, the properties of these indicators Limit their targeting to subcellular(More)
Loss of function mutations in granulin (GRN) are linked to two distinct neurological disorders, frontotemporal lobar degeneration (FTLD) and neuronal ceroid lipofuscinosis (NCL). It is so far unknown how a complete loss of GRN in NCL and partial loss of GRN in FTLD can result in such distinct diseases. In zebrafish, there are two GRN homologues, Granulin A(More)
