Protocols

Specificity / Sensitivity

LIN28A (D1A1A) XP® Rabbit mAb recognizes endogenous levels of total LIN28A protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro201 of human LIN28A protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from NTERA-2 cl.D1 and F9 cells using LIN28A (D1A1A) XP® Rabbit mAb.

IF-IC

IF-IC

Confocal immunofluorescent analysis of NTERA-2 cl.D1 (left) and HeLa (right) cells using Lin28A (D1A1A) XP® Rabbit mAb (green). Actin filaments were labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).

Background

LIN28A and LIN28B are conserved, developmentally regulated RNA binding proteins that inhibit the processing and maturation of the let-7 family of miRNAs (1,2). The let-7 miRNAs have been implicated in repression of oncogenes such as Ras, Myc, and HMGA2 (3). It has recently been shown that upregulation of LIN28A and LIN28B in primary human tumors and human cancer cell lines is correlated with downregulation of let-7 miRNAs (4). LIN28 genes are reported to be involved in primordial germ cell development and germ cell malignancy (5). In addition, allelic variation in LIN28B is associated with regulating the timing of puberty in humans (6). Overexpression of LIN28A, in conjunction with Oct-4, Sox2, and Nanog, can reprogram human fibroblasts to pluripotent, ES-like cells (7).
