Known Shoc2-interacting proteins, mapped to the N- or C-terminal region of Shoc2. Direct interaction of proteins in I and II with individual domains of Shoc2 was measured by yeast two-hybrid assay, binding assays using recombinantly expressed and purified GST-fusion proteins, or another biochemical strategy. Shoc2 LRR domain contains binding regions for PP1c (LRR4), the E3 ligases HUWE1 (LRR12-14), FBXW7 (LRR18), PSMC5 (LRRC), and VCP/p97 (LRR12-14). Proteins listed in III as ‘coimmunoprecipitated with Shoc2’ have not been shown to bind Shoc2 directly.
