sec-23 encodes a component of COPII (coat protein complex II)-coated vesicles orthologous to Saccharomyces cerevisiae Sec23p; by homology, SEC-23 is predicted to be involved in endoplasmic reticulum (ER)-to-Golgi transport; loss of sec-23 activity results in defects in oogenesis, morphogenesis, and extracellular matrix secretion; a SEC-23::GFP fusion protein localizes to the apical region of the endoplasmic reticulum of hypodermal cells, consistent with localization to endoplasmic reticulum exit sites.
Predicted to enable GTPase activator activity. Predicted to be involved in COPII-coated vesicle cargo loading. Located in endoplasmic reticulum exit site. Expressed in hypodermis. Human ortholog(s) of this gene implicated in Cowden syndrome 7; congenital dyserythropoietic anemia type II; and craniolenticulosutural dysplasia. Is an ortholog of human SEC23B (SEC23 homolog B, COPII coat complex component).

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
