초록

c-fos 유전자는 전사조절인자로서 주로 c-jun family와 결합하여 heterodimers를 형성하며 AP-1 조절 부위를 가지는 유전자들의 전사를 조절하는 것으로 알려져 있다. 이 유전자의 발현은 myoblasts를 비롯한 여러 세포의 분화와 성장을 조절하며 최근 돼지에서 육질에 영향을 미치는 근섬유와 관련된다는 보고가 있다. 본 연구는 소에서 육질과 c-fos 유전자와의 관계를 알아보기 위한 기초자료로서 총 1,443 bp의 mRNA 염기서열을 최초로 소에서 밝혔으며 여러 조직과 기관에서의 발현양상도 살펴보았다. 한우의 c-fos 유전자의 염기서열을 사람, 돼지 및 쥐와 비교하여 본 결과 각각 89.8%, 93.5%와 87.0%의 높은 상동성을 보였다. 이 유전자의 발현은 근육중 갈비에서 가장 많은 발현량을 보였고, 조직에서는 비장에서 가장 많은 발현량을 보이는 것을 알 수 있었다. 이 연구에서 밝혀진 c-fos 유전자는 SNP의 추가분석에 의해 한우에서 육질의 향상과 관련이 있는 후보유전자로 쓰일 수 있을 것으로 사료된다.

Cellular FOS(c-fos) protein is a transcription factor that forms heterodimers mostly with c-jun family and stimulates the transcription of genes containing AP-1 regulatory elements. This c-fos expression can control growth and differentiation of various precursor cells including myoblasts. The controls by c-fos gene have been identified for affecting skeletal muscle fiber traits which are the key determinants of meat quality in pigs. As a first step for identifying the relationship between c-fos gene and meat quality traits in cattle, we fully sequenced 1,443 bp of Hanwoo c-fos mRNA and analyzed expression patterns from various organs and muscle tissues. The sequence identities of Hanwoo c-fos with that of human, pig and mouse showed 89.8%, 93.3% and 87%, respectively. Analyses of the northern blot showed high c-fos expressions were obtained in spleen and rib muscle from 7 organs and 9 different parts of muscles investigated. These results presented here can be used as a valuable marker for meat quality related traits in cattle with further verification.
