Official Symbol: shn-1
Official Full Name: Protein shank
Primary source: WormBase:WBGene00006444
Locus tag: CELE_C33B4.3
See related: AllianceGenome:WB:WBGene00006444
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Caenorhabditis elegans (strain: Bristol N2)
Lineage: Eukaryota; Metazoa; Ecdysozoa; Nematoda; Chromadorea; Rhabditida; Rhabditina; Rhabditomorpha; Rhabditoidea; Rhabditidae; Peloderinae; Caenorhabditis
Summary: Predicted to enable ionotropic glutamate receptor binding activity and synaptic receptor adaptor activity. Involved in defecation and rhythmic behavior. Predicted to be located in cytoplasmic vesicle; pseudopodium; and synapse. Predicted to be active in dendritic spine and postsynaptic density. Predicted to colocalize with postsynaptic membrane. Is expressed in several structures, including epithelial cell; neurons; pharyngeal-intestinal valve; somatic nervous system; and sperm. Used to study autism spectrum disorder. Human ortholog(s) of this gene implicated in Phelan-McDermid syndrome; autistic disorder; and schizophrenia 15. Orthologous to several human genes including SHANK1 (SH3 and multiple ankyrin repeat domains 1). [provided by Alliance of Genome Resources, Dec 2024]

Shank promotes action potential repolarization by recruiting BK channels to calcium microdomains.

Regulation of Innate Immune Response to Fungal Infection in Caenorhabditis elegans by SHN-1/SHANK.
Title: Regulation of Innate Immune Response to Fungal Infection in Caenorhabditis elegans by SHN-1/SHANK.
Here the authors show that the Caenorhabditis elegans SHN-1/Shank binds L-type calcium channels and that increased and decreased shn-1 gene dosage alter L-channel current and activity-induced expression of a CRH-1/CREB transcriptional target (gem-4 Copine).
Title: Shank is a dose-dependent regulator of Ca(v)1 calcium current and CREB target expression.
Shank ANK repeat-domain along with PDZ may play a crucial role in regulating calcium signaling with inositol triphosphate receptor
Title: ANK repeat-domain of SHN-1 Is indispensable for in vivo SHN-1 function in C. elegans.
SHN-1 protein is localized in various tissues including neurons, pharynx and intestine. Suppression of SHN-1 did not cause lethality or developmental abnormality, but resulted in altered defecation rhythm in a strain with mutated IP(3)receptor.
Title: SHN-1, a Shank homologue in C. elegans, affects defecation rhythm via the inositol-1,4,5-trisphosphate receptor.
