Subunit: Component of the VCB (VHL-Elongin BC-CUL2) complex; this complex acts as a ubiquitin-ligase E3 and directs proteasome-dependent degradation of targeted proteins. Interacts with CUL2; this interaction is dependent on the integrity of the trimeric VBC complex. Interacts (via the beta domain) with HIF1A (via the NTAD domain); this interaction mediates degradation of HIF1A in normoxia and, in hypoxia, prevents ubiqitination and degradation of HIF1A by mediating hypoxia-induced translocation to the nucleus, a process which requires a hypoxia-dependent regulatory signal. Interacts with ADRB2; the interaction, in normoxia, is dependent on hydroxylation of ADRB2 and the subsequent VCB-mediated ubiquitination and degradation of ADRB2. Under hypoxia, hydroxylation, interaction with VHL, ubiquitination and subsequent degradation of ADRB2 are dramatically decreased. Interacts with RNF139, USP33 and JADE1. Found in a complex composed of LIMD1, VHL, EGLN1/PHD2, TCEB2 AND CUL2. Isoform 1 and isoform 3 interact with LIMD1 (via LIM zinc-binding 2), AJUBA (via LIM domains) and WTIP (via LIM domains). Interacts with EPAS1 Developmental stage: At 4-10 weeks pc, strong expression in the developing central nervous system, kidneys, testis and lung.

Function: UniProtKB/Swiss-Prot Summary: VHL_HUMAN, P40337 Function: Involved in the ubiquitination and subsequent proteasomal degradation via the von Hippel-Lindau ubiquitination complex. Seems to act as 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. Ubiquitinates, in an oxygen-responsive manner, ADRB2
