hgrs-1
Name
Hepatocyte Growth factor-Regulated TK Substrate (HRS) family 1
Synonyms
  • C07G1.5
  • CELE_C07G1.5
Biotype
protein coding gene
Automated Description
Enables ubiquitin binding activity. Involved in protein localization to non-motile cilium. Located in early endosome and endosome membrane. Part of ESCRT-0 complex. Is expressed in several structures, including coelomocyte; excretory canal; hermaphrodite gonad; intestine; and vulva. Orthologous to human HGS (hepatocyte growth factor-regulated tyrosine kinase substrate).
WB Description
hgrs-1 encodes a VHS and FYVE zinc finger-domain containing protein that is the C. elegans ortholog of S. cerevisiae Vps27p and mammalian hepatocyte growth factor-regulated tyrosine kinase substrate (HGS); hgrs-1 activity is essential for molting and thus for proper larval development; consistent with its proposed role in the endocytic pathway, HGRS-1 is also required for proper trafficking of the LRP-1 low-density lipoprotein receptor-related protein 1 and for endosome maturation and regulation of autophagic vesicle accumulation; an HGRS-1::GFP fusion protein is widely expressed, but particularly enriched in epithelial cells; within cells, HGRS-1::GFP localizes to endosomal membranes; HGRS-1 and STAM-1 physically interact in vivo, forming the C. elegans ESCRT-0 complex; on early endosomes; in the context of the complex, both STAM-1 and HGRS-1 bind ubiquitin.
