Summary: Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of ARF protein signal transduction. Located in midbody and nucleus. Is expressed in intestine; nervous system; rectal gland cell; and somatic cell. Orthologous to several human genes including CYTH4 (cytohesin 4). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

GRP-1 controls asymmetric divisions of certain neuroblasts that divide to produce a larger neuronal precursor or neuron and a smaller cell fated to die. GRP-1 interacts with CNT-2, EFA-6 and BRIS-1.
Title: Asymmetric neuroblast divisions producing apoptotic cells require the cytohesin GRP-1 in Caenorhabditis elegans.
