“…Isolation of a cDNA which is upregulated in 208F cells transformed with v-fos and v-ras A cDNA library representing the mRNAs which are upregulated in FBR cells compared to 208F cells was prepared using the suppression subtractive hybridization method (Diatchenko et al, 1996), and 500 random clones were sequenced (Johnston et al, 1999, unpublished). The open reading frame (ORF) from one 400 bp clone, designated krp1, showed 31% amino acid sequence identity to a Drosophila kelch protein, which is involved in crosslinking actin ®laments in the ring canals during development (Xue and Cooley, 1993;Robinson and Cooley, 1997).…”
