Jun Anticuerpo(d-230): sc-25763

---

Drosophila melanogaster is a proven and effective model for studying developmental and cellular processes common to higher eukaryotes. Approximately 13,600 genes have been elucidated from more than 120 megabases of euchromatin, and they are organized among the chromosomes 2, 3, 4, X and Y, with the Y chromosome being predominately heterochromatic (1). Drosophila genes can be categorized based on the type of protein they encode and are represented by six major classifications, which include intracellular signaling proteins, transmembrane proteins, RNA binding proteins, secreted factor≠s, transcription regulators (basic helix-loop-helix, homeodomain containing, zinc finger containing, and chromatin associated) or other functional proteins (2). Many of the genes expressed in Drosophila are structurally and functionally similar across species, as are the pathways involved in transducing intracellular signaling. Among these proteins, Jun is a transcription factor that participates in signaling pathways related to mammalian Ras, Raf, ERK cascades (3-6). Like members of the mammalian AP-1 class of transcription regulators, Drosophila Jun contains a DNA-binding domain consisting of a leucine zipper and an adjacent basic region (3-6).
