Expression analysis of KBP. A, amino acid sequence of KBP, probable TPR repeats are boxed. B, expression of KBP mRNA in various human tissues was analysed by Northern blot hybridization using the complete cDNA as a probe. The size marker is indicated in kilobase. C, expression of KBP in human, mouse and hamster cell lines. Triton cell lysates were separated by SDS-PAGE, transferred to nitrocellulose and immunoblotted using the KBP antiserum. Size markers are indicated in kDa.
