Trapped gene association determined by genome coordinate overlap and strand. The mouse YHB-130 embryonic stem cell line contains an in frame beta-geo (beta-galactosidase-neomycin-phosphotransferase II) insertion between exons 16 and 17, which leads to the expression of a fusion protein encompassing amino acid residues 1 to 548 (out of 1692 amino acids) fused to beta-geo. Northern blot and Western blot confirmed the presence of the larger transcript and the fusion protein. (J:153790)
