86-7932-99 ［取扱停止］Human Elongin B&Elongin C&VHL Heterotrimer Protein, Strep II Tag&Strep II Tag&His Tag (MALS verified) 100ug ELL-H5595
特徴
- Background：Elongin B (ELOB) and Elongin C (ELOC) form a heterodimer that serves as the regulatory subunit for the Elongin complex--a general transcription elongation factor that increases RNA Polymerase II transcription through template-encoded arresting sites.
- The ELOB/ELOC complex also binds to the "BC-box motif" found in many proteins in the VHL-box and SOCS-box protein families.
- In this function, ELOB/ELOC serves as an adapter between substrate recognition proteins and either Cullin-2/Rbx1 (in VHL-box E3 Ubiquitin ligases) or Cullin-5/Rbx2 (in SOCS-box E3 Ubiquitin ligases).
- VHL is involved in the ubiquitination and subsequent proteasomal degradation via the von Hippel-Lindau ubiquitination complex.
- It seems to act as a target recruitment subunit in the E3 ubiquitin ligase complex and recruits hydroxylated hypoxia-inducible factor (HIF) under normoxic conditions.
- Involved in transcriptional repression through interaction with HIF1A, HIF1AN and histone deacetylases.

- Characteristics：Human Elongin B&Elongin C&VHL Heterotrimer Protein, Strep II Tag&Strep II Tag&His Tag, produced by co-expression of Elongin B and Elongin C and VHL, has a calculated MW of 14.5 kDa (Elongin B) and 13.8 kDa (Elongin C) and 25.8 kDa (VHL). Subunit Elongin B is fused with a Strep II tag at the N-terminus and Elongin C is fused with a Strep II tag at the N-terminus and VHL is fused with a polyhistidine tag at the N-terminus. The protein migrates as 17 kDa (Elongin B) and 14 kDa (Elongin C) and 30 kDa (VHL) under reducing (R) condition (SDS-PAGE) due to glycosylation.
