| Research Abstract |
We have isolated a MEKA cDNA clone by differential colony hybridization method. The MEKA cDNA encodes unknown soluble protein whose molecular weight and pI are calculated to be 27KDa and 5.35, respectively. We found by Northern and in situ hybridization that MEKA mRNA was transcribed only in the photoreceptor cells. The MEKA cDNA was ligated with expression vector PEX1 and a MEKA-fusion protein synthesized in E.coli was purified and used as antigen. By the Western blot and immunohistochemical study, we found that MEKA protein is expressed in the photoreceptor cells, but not in other tissues.
