Function

The protein expressed by the SQSTM1 gene is an autophagy receptor essential for selective macroautophagy (aggrephagy). It acts as a bridge between polyubiquitinated cargo and autophagosomes, interacting with both the cargo and an autophagy modifier from the MAP1 LC3 family. Alongside WDFY3, it plays a role in forming and autophagically degrading cytoplasmic ubiquitin-containing inclusions and recruiting ubiquitinated proteins to nuclear PML bodies. SQSTM1 may regulate NFKB1 activation by TNF-alpha, nerve growth factor (NGF), and interleukin-1, and may influence titin/TTN signaling in muscle cells. It may also affect signaling cascades via ubiquitination and be involved in cell differentiation, apoptosis, immune response, and regulation of potassium channels. The protein is involved in endosome organization by retaining vesicles in the perinuclear cloud; ubiquitination by RNF26 allows it to attract vesicle-associated adapters, forming a molecular bridge to organize endosomal pathways. Additionally, it promotes the relocalization of Lys-63-linked ubiquitinated STING1 to autophagosomes and acts as an activator of the NFE2L2/NRF2 pathway by interacting with KEAP1, which inactivates the BCR(KEAP1) complex, resulting in nuclear accumulation of NFE2L2/NRF2 and expression of cytoprotective genes.

Post-translational modifications

Phosphorylation at Ser-407 by ULK1 destabilizes the UBA dimer interface and increases binding affinity to ubiquitinated proteins (By similarity). Phosphorylation at Ser-407 also primes for subsequent phosphorylation at Ser-403 (By similarity). Phosphorylation at Ser-403 by CK2 or ULK1 promotes binding to ubiquitinated proteins by increasing the affinity between the UBA domain and polyubiquitin chains (PubMed:22017874, PubMed:25040165). Phosphorylation at Ser-403 by ULK1 is stimulated by SESN2 (PubMed:25040165). Phosphorylated at Ser-403 by TBK1, leading to promote relocalization of 'Lys-63'-linked ubiquitinated STING1 to autophagosomes (PubMed:29496741). Phosphorylation at Ser-349 by ULK1 promotes interaction with KEAP1 and inactivation of the BCR(KEAP1) complex, promoting NFE2L2/NRF2 nuclear accumulation and expression of phase II detoxifying enzymes (PubMed:37306101). Phosphorylated in vitro by TTN (PubMed:15802564).
