e678 : about 50% longer than wildtype at all stages. ES3. Male bursa slightly elongated ME3 (ME0 at 25x?). NA5 (e405 e434 etc. : similar phenotype to e678).
[C.elegansII] e678 : about 50% longer than wildtype at all stages; some embryonic lethality; ES3. Male bursa slightly elongated, ME3 (ME0 at25C?). OA4: e405, e434, n1346, n1630 etc. (allsimilar to e678). [Brenner 1974]
lon-2 encodes a member of the glypican family of heparan sulfate proteoglycans; during development, lon-2 activity is required in the hypodermis for negative regulation of the DBL-1/BMP signaling pathway that regulates body length; genetic analyses indicate that lon-2 functions upstream of dbl-1, and in vitro studies show that LON-2 can bind mammalian BMP2, suggesting that LON-2 may directly interact with DBL-1 to negatively regulate DBL-1/BMP signaling; in addition to expression in hypodermis, LON-2 is expressed strongly in the intestine, particularly the anterior and posterior cells; LON-2 localizes to the cell surface.
Enables growth factor binding activity. Involved in several processes, including negative regulation of transmembrane receptor protein serine/threonine kinase signaling pathway; regulation of cell migration; and regulation of mesodermal cell fate specification. Located in cell surface. Expressed in hypodermis and intestine.
