Paracentrotus lividus Genes in Development:
Butanol - extractable proteins
bep3
Function
bep3 is a member of a multigenic family, coding for butanol-extractable proteins.
In sea urchin embryos butanol treatment extracts cell surface proteins including
the constituents of a 22S particle called toposome, which is believed
to play a role in cell interactions (Di Carlo et al., 1990, Montana et al., 1997).
Protein
bep3 is a butanol-extractable protein (Di Carlo et al., 1990).
GenBank: 1220432
Subcellular location
bep3 belongs to cell surface proteins (Di Carlo et al., 1990, Montana et al., 1997).
Expression Pattern
bep3 mRNA is present, although, in different amounts, in all the
developmental stages.
bep3 maternal messengers are localized
in the animal part of P. lividus egg and embryos
It was demonstrated that bep3 mRNA is associated with the
cytoskeleton elements and that this association is necessary for its
localization (Montana et al., 1997).
