What pLDDT means and how to read it

Function

Plays a role in intracellular protein trafficking and degradation (PubMed:11707463, PubMed:14570915, PubMed:15358775). May regulate CFTR chloride currents and acid-induced ASIC3 currents by modulating cell surface expression of both channels (By similarity). May also regulate the intracellular trafficking of the ADR1B receptor (PubMed:15358775). May play a role in autophagy (By similarity). Together with MARCHF2 mediates the ubiquitination and lysosomal degradation of CFTR (PubMed:23818989). Overexpression results in CFTR intracellular retention and lysosomaldegradation in the lysosomes (PubMed:11707463, PubMed:14570915)

Subunit structure

Homooligomer (By similarity). Interacts with FZD5 (By similarity). Interacts with FZD8 (PubMed:16882988). Interacts with GRID2 and BECN1 (By similarity). Interacts with CSPG5 (By similarity). Interacts with CLCN3 (By similarity). Interacts with STX6 (PubMed:11384996). Interacts with CFTR (PubMed:11707463). Interacts with ASIC3 (PubMed:15317815). Interacts with GOLGA3 (PubMed:15951434).
