* Information From OMIM
Function: Pregnenolone (PREG) and a synthetic analog, MePREG, bind to MAP2 and stimulate microtubule polymerization. Fontaine-Lenoir et al. (2006) found that PREG, MePREG, and progesterone (PROG), the metabolite of PREG, significantly enhanced neurite outgrowth of NGF (see NGFB; OMIM:162030)-treated rat PC12 pheochromocytoma cells. Map2 RNA interference prevented the stimulatory effect of PREG and MePREG, but not PROG, on neurite extension. Fontaine-Lenoir et al. (2006) concluded that MAP2 is a specific PREG and MePREG receptor.
