Synonyms:CSDD2, FLJ16517, lin 28 homolog B(C. elegans), Lin 28B, Lin28, LIN28B, Protein lin 28 homolog B Background:LIN28B, also named as CSDD2, belongs to the lin-28 family. Acts as a suppressor of microRNA(miRNA) biogenesis by specifically binding the precursor let-7(pre-let-7), a miRNA precursor. Lin2B is stage-specifically expressed in embryonic muscle, neurons, and epithelia, as well as in embryonic carcinoma cells, however, it is suppressed in most adult tissues except for skeletal and cardiac muscle. Lin28B shares 78 % sequence identity with LIN28A, with some unknown functions. This antibody is specific to LIN28B.
