2. Authors demonstrate a novel mode of regulation of the Keap1-Nrf2 system, mediated by a splicing variant of p62/Sqstm1 pre-mRNA. Ensembl database searches and subsequent biochemical analyses of mice revealed the presence of an mRNA that encodes a p62/Sqstm1 protein lacking the Keap1-interacting region (KIR), which is essential for the interaction with Keap1.

13. the complex structures between the ZZ-domain of p62 and various type-1 and type-2 N-degrons, are reported.

14. the role of p62 in energy metabolism was studied in fibroblasts.

15. p62 and ubiquitinated proteins spontaneously coalesce into larger clusters. Efficient cluster formation requires substrates modified with at least two ubiquitin chains longer than three moieties and is based on p62 filaments cross-linked by the substrates.

16. 27-OH induced autophagy is dependent on the relation between nuclear factor erythroid 2 p45-related factor 2 (Nrf2)-dependent antioxidant response and p62.

17. our results showed that high CD44 led to p62-associated NRF2 activation in CD44(high) breast CSC-like cells. NRF2 activation contributed to the aggressive phenotype, tumor growth, and anticancer drug resistance of CD44(high) CSCs

18. results suggested that p62 plays a protective role in adipogenesis of human adipose-derived stromal cells through regulating mitophagy.

19. The results of the present study demonstrated that p62 may aggravate LPSinduced acute kidney injury in mice by promoting apoptosis in renal tubular epithelial cells.

20. Study supports HuR's role as an upstream regulator of p62 expression in ARPE-19 cells, helps to understand better the early events in response to a proautophagy stimulus.

Mouse (Murine) Sequestosome 1 (SQSTM1) interaction partners

1. Authors demonstrate a novel mode of regulation of the Keap1-Nrf2 system, mediated by a splicing variant of p62/Sqstm1 pre-mRNA. Ensembl database searches and subsequent biochemical analyses of mice revealed the presence of an mRNA that encodes a p62/Sqstm1 protein lacking the Keap1-interacting region (KIR), which is essential for the interaction with Keap1.

2. the effect of the p62 P394L mutation on osteoclastogenesis and bone morphometry in relation to ageing, the natural history of lesion progression in p62(P394L) mice, is reported.

3. Drp1-dependent mitochondrial fission regulates p62-mediated autophagy in LPS-induced activated microglial cells

4. Here we show that Ulk2 heterozygous (Ulk2+/-) mice have upregulated expression of sequestosome-1/p62, an autophagy-associated stress response protein, predominantly in pyramidal neurons of the prefrontal cortex (PFC), and exhibit behavioral deficits associated with the PFC functions, including attenuated sensorimotor gating and impaired cognition

5. Autophagy through p62 plays an important role in regulating insulin receptor substrate 1 protein levels in response to nutritional deficiency. The present findings suggest that autophagy might function as energy depletion-sensing machinery that finely tunes insulin signal transduction.

6. These results indicate that p62 predominantly suppresses murine in vitro osteoclast differentiation and highlight previously undetected Paget's disease-like phenotypes in p62(-/-) mice in vivo.

7. the essential role that p62, particularly its PB1 and UBA domains, has in the formation of ALIS.

8. Cereblon suppresses the formation of pathogenic protein aggregates in a p62-dependent manner.

9. A complex of C9ORF72 and p62 uses arginine methylation to eliminate stress granules by autophagy.

10. Atg7(f/f) Tyr-Cre mice, in which autophagy-related 7 (Atg7) is conditionally deleted under the control of the tyrosinase promoter, are a model for accumulations of the autophagy adapter and substrate sequestosome-1/p62 in both neuronal and neuroepithelial cells.

11. These results suggest that overexpression of SQSTM1 in SOD1 (H46R) mice accelerates disease onset by compromising the protein degradation pathways.
