SCHLAP1 and prostate carcinoma: The MER52A sequence not only contains a functional regulatory promoter for lncMER52A, and the initial exon of lncMER52A also originates from the 3’ terminal of the MER52A element, which is similar to the LTR12C-derived SChLAP1 in prostate cancers (Prensner et al., 2013).
