CDC-2-like kinase 1 (CLK1) plays a critical role in regulating pre-RNA splicing and post-transcriptional gene expression. Two distinct transcripts of the porcineCLK1gene, known as full-lengthCLK1and truncatedCLK1(CLK1T), were identified byin silicocloning, RT-PCR, and RACE. The entire cDNA sequence of full-lengthCLK1was 1771 bp, containing a 1455 bp ORF encoding a deduced protein of 484 amino acids. The complete cDNA sequence ofCLK1Tis 1680 bp, containing a 414 bp ORF encoding a deduced protein of 137 amino acids. The genomic structure and sequence of porcineCLK1were analyzed using a bacterial artificial chromosome clone of a Chinese Erhualian pig, with 13 exons and 12 introns spanning approximately 9 kb. RT-PCR revealed that the full-length and truncated splice forms were expressed at equivalent levels in pig heart, fat, liver, spleen, and lymph tissues. The full-length splice form was expressed at a much higher level than the truncated form in tissues of the pig cerebrum, longissimus dorsi, small intestine, and kidney. TheCLK1gene was physically assigned to SSC 15 between microsatellite markersSW1316andSW2083using the IMpRH panels.
