Abstract

The objective of the study was to clone full-length cDNA of Cdc42(Cell division cycle 42) gene of buffalo and analyze this gene.RT-PCR were performed to clone Cdc42 cDNA from buffalo, and the cloned Cdc42 cDNA sequence had been sent to GeneBank and got a accession number:JN380079.The bioinformatics analysis results showed that the Cdc42 cDNA sequence was 626 bp length,containing an open reading frame of 576 bp,encoding 191 amino acids.Relative molecular weight was 21.3 kD,pI was 6.16.Further analysis results indicated that the homology of Cdc42 gene of buffalo are 99.65%, 96.70%, 94.97% and 94.10%, compared to cattle, dog, mouse and human, respectively; the protein was non-transmembrane protein, which include a RHO domain. These results set a strong basis for further research of the function of Cdc42 of buffalo.
