Abstract

Signal transducer and activator of transcription 5A (STAT5A) is a crucial signaling protein mediating the biological effects of prolactin hormone which in turn activates the transcription of milk proteins genes. In order to study the POLYMORPHISMs ofSTAT5A gene total blood samples were collected randomly from one hundred of Holstein and Simmental cattle. DNA was extracted using modified salting out method and polymerase chain reactions (PCR) were carried out using a specific primer pairs for amplification a fragment of 281 bp from part of exon 15 and intron 16 ofSTAT5A gene. All of individuals were genotyped by single stranded conformation POLYMORPHISM (SSCP) analyses using silver staining. Two SSCP patterns of A and B were identified with the frequency of 0.91 and 0.09 and 0.88 and 0.12 in Holstein and Simmental cattle, respectively. Two genotypes of AA (0.82) and AB (0.18) were found in Holstein and AA (0.76) and AB (0.24) in Simmental individuals. The results revealed that the marker site of STAT5A gene is polymorph in studied Holstein and Simmental cattle and the SSCP technique has a great potential for detection of such POLYMORPHISM. Furthermore, a comparison of gene and genotype frequencies showed no any statistical differences (P>0.05) between Holstein and Simmental cattle breed that have genotyped in the present study.
