Cloning by differential screening of a Xenopus cDNA that encodes a kinesin-related protein.

Abstract

By differential screening of a Xenopus egg cDNA library, we selected nine clones (Eg1 to Eg9) corresponding to mRNAs which are deadenylated and released from polysomes soon after fertilization. The sequence of one of these clones (Eg5) revealed that the corresponding protein has the characteristic features of a kinesin-related protein. More specifically, Eg5 was found to be nearly 30% identical to a kinesin-related protein encoded by bimc, a gene involved in nuclear division in Aspergillus nidulans.
