Description of "C29E4.3" |
ran-2 encodes the C. elegans RanGAP (GTPase activating protein) homolog, conserved amongst yeast, Drosophila (segregation distorter), Xenopus, and humans; by homology, RAN-2 is predicted to function as a key regulator of the Ran GTP/GDP cycle by stimulating the otherwise weak Ran GTPase activity; in C. elegans, RAN-2 activity is essential during early embryogenesis for comigration of centrosomes with the male pronucleus, mitotic spindle formation, chromosome segregation, and nuclear envelope assembly; in addition, RAN-2 is also required for nucleocytoplasmic transport; ran-2 reporter gene expression is detected in embryos and larvae, although the precise subcellular localization is not yet known. |
