Summary
Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in negative regulation of stress fiber assembly; protein localization to cell-cell junction; and regulation of Rho protein signal transduction. Predicted to act upstream of or within actin cytoskeleton organization; regulation of cell shape; and small GTPase-mediated signal transduction. Predicted to be located in apical part of cell and cytosol. Predicted to be active in plasma membrane. Is expressed in brain; genitourinary system; integument; and liver. Human ortholog(s) of this gene implicated in retinitis pigmentosa. Orthologous to human ARHGEF18 (Rho/Rac guanine nucleotide exchange factor 18). [provided by Alliance of Genome Resources, Nov 2024]

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.
