Predicted to enable mRNA binding activity. Predicted to be involved in positive regulation of stress granule assembly and protein homooligomerization. Predicted to act upstream of or within small GTPase mediated signal transduction. Predicted to be located in cytoplasmic stress granule. Predicted to be part of ribonucleoprotein complex. Predicted to be active in cytosol. Is expressed in several structures, including central nervous system; ovary; sensory organ; and tooth. Orthologous to human G3BP2 (G3BP stress granule assembly factor 2). [provided by Alliance of Genome Resources, Apr 2022]
