The alternative splicing of in .

Alternative splicing largely enhanced the diversity of transcriptome and proteome in eukaryas. Along with technological development, more and more genes are reported to be alternatively spliced during mRNA maturation. Here, I report the alternative splicing of () and its special splicing site in . was predicted to be alternatively transcribed into two variants, and , which encoded a GPI-anchored protein and a soluble secretory protein, respectively. But, according to experimental data, instead of , a novel variant, , which encodes a protein with a transmembrane region at its C-terminus, was demonstrated. Interestingly, it exhibites a different organ-specific expression pattern with , and an unusual intron splicing site not following 'GT-AG' rule or any reported rule.
