Structure of the VHL-ElonginC-ElonginB complex: implications for VHL tumor suppressor function.

Chains	Pfam Accession	Pfam Identifier	Pfam Description	Type	Source
A	PF00240	ubiquitin	Ubiquitin family	Domain	This family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260). A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5]. PFAM PF00240
C	PF01847	VHL	von Hippel-Lindau disease tumour suppressor protein	Domain	VHL forms a ternary complex with the elonginB Swiss:O44226 and elonginC Swiss:O13292 proteins. This complex binds Cul2, which then is involved in regulation of vascular endothelial growth factor Swiss:P15692 mRNA. PFAM PF01847
B	PF03931	Skp1_POZ	Skp1 family, tetramerisation domain	Domain	PFAM PF03931
