Two Types of New Ferritin cDNA Sequences from Xenopus laevis Germinal Vesicle Oocytes

Abstract

Some of Xenopus ferritin cDNA family genes have already been sequenced. In this study, we report that two ferritin cDNA genes have been cloned from the Xenopus laevis germinal vesicle (GV) oocytes. The deduced proteins have different lengths with varied sequences when compared with the published Xenopus ferritins. One of them is the ferritin light chain homologous (LCH), which is reported for the first time in Xenopus and the other is the ferritin heavy chain homologous (HCH) that is first reported in Xenopus GV oocyte.
