Summary
Enables guanyl-nucleotide exchange factor activity. Acts upstream of or within establishment of epithelial cell polarity. Located in bicellular tight junction; cytosol; and plasma membrane. Is extrinsic component of cytoplasmic side of plasma membrane. Is expressed in brain; sciatic nerve; and spinal cord. Orthologous to human CYTH1 (cytohesin 1).

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.
