Protein

Ras-like GTP-binding protein rhoA

Gene

rho-1

Organism
Caenorhabditis elegans
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Required for ventral migration of epidermal cells during ventral enclosure in the embryo and for cell elongation. Also required for ventral migration of P cells during larval development. Involved in asymmetric spindle positioning during anaphase and establishment of cell polarity during embryo development. In adults, involved in regulation of multiple processes including locomotion, pharyngeal pumping, fecundity, ovulation, defecation and body morphology.4 Publications

Disruption phenotypei

RNAi-mediated knockdown of the protein causes embryonic arrest in most cases with development of elongation-defective uncoordinated kinky larvae from embryos which escape arrest. Defective ventral migration of P cells leading to defective gonad development. Defective establishment of anterior-posterior cell polarity in one-cell embryos.3 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
