Enables identical protein binding activity and unfolded protein binding activity. Involved in several processes, including GABAergic synaptic transmission; chaperone-mediated protein folding; and establishment of organelle localization. Predicted to be located in cytoplasm. Expressed in gonad; hypodermis; intestine; and neurons. Used to study epilepsy and lissencephaly. Is an ortholog of human NUDC (nuclear distribution C, dynein complex regulator).
In humans, mutations in the LIS1 gene (Platelet activating factor acetylhydrolase, isoform 1B, alpha subunit; PAFAH1B1) and the LIS1 pathway, are implicated in Lissencephaly, a developmental abnormality associated with a failure of neuronal migration in the cerebral cortex, leading to mental retardation and epilepsy; human NDE1 and NDEL1, are effectors of LIS1; the elegans genetic model for epileptic siezures consists of lis-1 mutants that are responsive to the common seizure inducer pentylenetetrazole (PTZ) and diplay a distinct convulsive phenotype; worms depleted for LIS1 pathway components via RNA interference (NUD-1, NUD-2, DHC-1, CDK-5, and CDKA-1) also exhibited significant convulsions following PTZ treatment; further nud-1 (orthologous to human NUDC), nud-2/NDE1 and cdk-5 show significant enhancement in convulsions in a lis-1 heterozygous background when compared with the wild-type background; these animals are also less likely to recover when PTZ treatment is removed, when compared to wild-type; these studies show that while knocking down target genes (lis-1, cdk-5, and cdka-1 that function in neuronal migration), and their interacting proteins like nud-1, nud-2 and dhc-1, does not yield spontaneous convulsions in C. elegans, further alterations in the neural environment through the application of PTZ serve to pass a critical threshold within these animals.
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
