Background Information

WSB1 (or SWIP1) gene encodes WD repeat and SOCS box-containing protein 1, a member of the WD-protein subfamily. It contains several WD-repeats spanning most of the protein and an SOCS box in the C-terminus. Alternatively spliced transcript variants encoding 3 distinct isoforms have been found for this gene. WSB1 serves as a probable substrate-recognition component of a SCF-like ECS (Elongin-Cullin-SOCS-box protein) E3 ubiquitin ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Ubiquitination and degradation of homeodomain-interacting protein kinase 2 by WSB1 has been reported (PMID: 15965468), initiated by the interaction of the two components (PMID: 18093972). WSB1 is also a part of an E3 ubiquitin ligase for the thyroid-hormone-activating type 2 iodothyronine deiodinase (D2) (PMID: 15965468).
