FGF3 from Xenopus laevis.

“…In this context, it is interesting to note that expression patterns of FGFR-2 in Xenopus embryos are very similar to those of XFGF3 (Friesel and Brown, 1992), consistent with the functional associations we report here. However, there are also clear discrepancies between the two patterns, as well as preliminary indications that XFGF3 is a potent inducer of mesoderm in animal cap explants before FGFR-2 is detectably expressed (Friesel and Brown, 1992;D.Tannahill and J.Slack, personal communication). The ability of XFGF3 to interact with other FGFRs would clearly explain such discrepancies.…”

“…Other members of the FGF family, such as FGF3 (formerly int-2) and FGF4 (formerly hst or kFGF), have also scored positively in mesoderm induction assays in vitro but with quite different efficiencies (Paterno et al, 1989). Only the mammalian Oxford University Press proteins were available for such assays but it is now clear that the Xenopus genome encodes homologues of several FGFs as well as FGF receptors (Kimelman et al, 1988;Volk et al, 1989;Musci et al, 1990;Friesel and Dawid, 1991;Friesel and Brown, 1992). For example, a recently described Xenopus gene, designated eFGF, specifies a protein that has similarities to both FGF4 and FGF6 .…”
