Sequestosome 1

Sequestosome-1 is a protein that in humans is encoded by the SQSTM1 gene.[5][6][7] Also known as the ubiquitin-binding protein p62,[8] it is an autophagosome cargo protein that targets other proteins that bind to it for selective autophagy. By interacting with GATA4 and targeting it for degradation, it can inhibit GATA-4 associated senescence and senescence-associated secretory phenotype.[9]

Model organisms have been used in the study of SQSTM1 function. A conditional knockout mouse line, called Sqstm1^{tm1a(KOMP)Wtsi}[15][16] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[17][18][19]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[13][20] Twenty two tests were carried out on homozygous mutant mice and one significant abnormality was observed: females had abnormal complete blood count parameters, including an increased red blood cell distribution width and increased mean platelet volume.[13]

Interactions

Sequestosome 1 has been shown to interact with:

• MAP1LC3A,[21]
• PRKCI,[22]
• RAD23A,[23]
• RIPK1,[24]
• TRAF6[25]
• TrkA,[26][27][28][29] and
• TrkB.[27][28]
• Nrf2 [30]
