Summary: Enables cell adhesion molecule binding activity and protein homodimerization activity. Involved in cell-cell signaling; nervous system development; and protein localization to synapse. Predicted to be located in membrane and synapse. Predicted to be active in cell-cell junction and plasma membrane. Is expressed in several structures, including P6.p hermaphrodite; P6.pa; P6.paa; egg-laying apparatus; and neurons. Used to study nephrotic syndrome. Human ortholog(s) of this gene implicated in nephrotic syndrome type 1. Orthologous to human NPHS1 (NPHS1 adhesion molecule, nephrin). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Through a series of biochemical, biophysical, and in vivo functional experiments, study finds that the extracellular affinity, docking geometry, and rigidity of the SYG-1 and SYG-2 ectodomains play crucial roles in specifying a functional synaptic architecture in C. elegans.
Title: Extracellular architecture of the SYG-1/SYG-2 adhesion complex instructs synaptogenesis.
Data show that the nephrin/Neph1 orthologs SYG-2 and SYG-1 form intercellular contacts strictly in trans between epithelial guidepost cells and neurons specifying the localization of synapses.
Title: Functional and spatial analysis of C. elegans SYG-1 and SYG-2, orthologs of the Neph/nephrin cell adhesion module directing selective synaptogenesis.
