is a monoallelically expressed long intergenic noncoding RNA located in the cattle cluster.

Long noncoding RNAs (lncRNAs) are important regulators of biological processes, and regulate genomic imprinting in and/or to induce monoallelic expression with parent-origin-specific pattern. domain is one of the largest imprinted clusters in mammals, and maternally expressed noncoding RNAs of this region is related to the pluripotency of the embryonic stem cells. Previously, we sequenced the cDNA of two maternally expressed noncoding RNAs, and , and mapped a lncRNA () between the two genes in the cattle domain on chromosome 21. In this study, we identified , a novel long intergenic noncoding RNA (lincRNA), which was also located between and . We identified four variants of LINC24065 (, , and ) that were a result of alternative splicing from 18 exons. and showed tissue-specific expression patterns in adultbovine tissues, and and were detected in all eight analysed tissues (heart, liver, spleen, lung, kidney, skeletal muscle, adipose and brain). Using single-nucleotide polymorphism (SNP)-based method, was identified to have monoallelic expression in adult tissues, suggesting that it is imprinted in cows. These results provide a foundation for further investigation about whether plays a role in regulating imprinting of the domain.
