Descripción

General description

Transcription factor Jun-B (UniProt: P09450; also known as MyD21) is encoded by the Junb (also known as Jun-b) gene (Gene ID: 16477) in mouse. JunB is a member of the AP-1 transcription family that binds to the DNA sequence 5′-TGA[CG]TCA-3′ and is involved in regulating gene activity following the primary growth factor response. It can bind to DNA either as a homodimer or as a heterodimer with another member of the Jun/Fos family. JunB plays an important role in proliferation, differentiation, and death. With respect to cell cycle control, JunB is reported to have a dual function. It can serve as a cell division inhibitor and a tumor suppressor or can promote cell division. It is reported to diminish cell proliferation via transcriptional activation of p16 (INK4a). Its expression is shown to be very low in quiescent cells but can be rapidly induced by mitogenic stimuli during the G0/G1 transition. It induces proliferation, survival, drug resistance in multiple myeloma (MM) cells and silencing of JunB is reported to block MM cell proliferation in a murine xenograft model. It also protects MM cells against dexamethosome and bortezomib-induced cell death. JunB is also reported to regulate epidermal stem cells and sebaceous glands through balancing proliferation and differentiation of progenitors and by suppressing lineage infidelity.
