Summary: Predicted to enable phosphatidylinositol binding activity; protein dimerization activity; and signaling receptor binding activity. Involved in neuron projection development. Acts upstream of or within negative regulation of transforming growth factor beta receptor signaling pathway. Located in several cellular components, including dendritic spine; early endosome; and postsynaptic density. Is active in postsynaptic density, intracellular component. Is extrinsic component of postsynaptic endosome membrane. Is expressed in embryo; epiblast; primitive endoderm; and yolk sac. Orthologous to human SNX1 (sorting nexin 1).

Data suggest that both, N-terminal and C-terminal region of SNX1 play critical role in the normal trafficking of the group I metabotropic glutamate receptors (mGlur1). In addition, study shows that SNX1 regulates the trafficking of mGluR1 through the interaction with hepatocyte growth factor-regulated tyrosine kinase substrate.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
