CFTR Associated Ligand (CAL) PDZ domain bound to HPV18 E6 oncoprotein C-terminal peptide (RLQRRRETQV)

Template:ABSTRACT PUBMED 24210758

Disease

[GOPC_HUMAN] Note=A chromosomal aberration involving GOPC is found in a glioblastoma multiforme sample. An intra-chromosomal deletion del(6)(q21q21) is responsible for the formation of GOPC-ROS1 chimeric protein which has a constitutive receptor tyrosine kinase activity.[1]

Function

[GOPC_HUMAN] Plays a role in intracellular protein trafficking and degradation. May regulate CFTR chloride currents and acid-induced ASIC3 currents by modulating cell surface expression of both channels. May also regulate the intracellular trafficking of the ADR1B receptor. May play a role in autophagy. Overexpression results in CFTR intracellular retention and degradation in the lysosomes.[2] [3] [4] [VE6_HPV18] Transcriptional transactivator. Binds double stranded DNA (By similarity). Has transforming activity. Inactivates, with E6-AP ubiquitin-protein ligase, the human p53/TP53 tumor suppressor protein by targeting it to degradation. Binds and targets human MUPP1/MPDZ protein to degradation. Those two functions presumably contribute to transforming activity. Interaction with human FBLN1 protein also seems to be linked to cell transformation.

About this Structure

4jor is a 4 chain structure. Full crystallographic information is available from OCA.
