General, if on one particular hand mitophagy failure leads to p62 accumulation and Affiliation with α-synuclein and PD pathogenesis, Alternatively, p62 is fundamental along with parkin and pink1 to keep up neuronal homeostasis and survival.
A street with very few comprehensive cans implies the collection provider is Operating efficiently. However, a Road lined with overflowing trash cans signals a breakdown from the system, indicating a dilemma in waste removing.
Ubiquitin-Proteasome Program: P62 has a superior affinity for ubiquitinated proteins. Its interaction within This method highlights its function in tagging proteins for degradation.
In most cancers biology, p62 has a dual part which will promote either tumorigenesis or tumor suppression dependant upon the context. Its function in cell signaling networks influences cell development and survival. In a few cancers, elevated levels of p62 are linked to intense tumor features.
Current evidences guidance a fascinating interaction between p62 and NF-κB mediated signalling, which may be decisive to balance autophagy with traditional apoptosis.
Investigate over time has even further elucidated its designation being an autophagy receptor. This historic standpoint highlights the evolving idea of P62, shifting from an easy protein to some significant mediator in a number of biological procedures.

Among selective cargoes, poly-ubiquitin tagged proteins are recognized by specific adaptors or alternatively transmembrane receptor proteins directly bind to cargoes without demanding ubiquitin [eight]. Scientific tests on selective protein degradation expose a vital function of p62 in autophagic digestion of poly-ubiquitinated protein cargo [9]. In the early ways of autophagosome development, a dimeric kind of p62 is phosphorylated in Ser407 by Atg1/ULK1 kinase, one of many upstream ATG gene products that trigger the autophagic flux. This phosphorylation destabilizes the p62 dimer and renders the protein liable to bear subsequent phosphorylation by other kinases (casein kinase2 or TANK-binding kinase1) to raise the binding affinity of p62 for ubiquitin chains [10]. It is actually renowned that p62 can preferentially bind to specified ubiquitin chain varieties which could symbolize a subtle standard of regulation for the duration of selective autophagy. Typically, while Lys48-connected ubiquitin chains are acknowledged via the 26S proteasome, Lys63-connected ubiquitin chains can also be affiliated with selective autophagy and so are preferentially recognized by p62 [eleven].
One of P62’s essential attributes is its signaling ability; it manages the interactions in between unique cellular parts. These interactions are vital in lots of mobile contexts, especially underneath circumstances of pressure or nutrient starvation.
Figure 2. Non-canonical Nrf2 activation by p62. Underneath non-pressured situations, the cytoprotective transcription component Nrf2 is continuously degraded through the proteasome on Keap1-mediated ubiquitination. Oxidation of regulatory cysteine p62 com residues of Keap1 in situations with oxidative and electrophilic anxiety inhibits Keap1 and ubiquitination of Nrf2 resulting in canonical Nrf2 activation and induction of target gene expression.
Recent developments highlight the importance of multidisciplinary methods in P62 analysis, combining genetic, biochemical, and imaging tactics to unravel its intricate biology.
Figure 4. p62 regulates and inbound links central pathways in inflammation and most cancers enhancement. p62 is a crucial cargo receptor for autophagy and mitophagy and so inhibits inflammasome activation and inflammation.
Important reports have focused on P62’s function in various health conditions. Investigations during the early 2000s connected P62 to neurodegenerative ailments and identified its accumulation in pathological configurations.
Minimal expression of p62 has been found in quite a few types of Advertisement and p62 lack of function has become revealed to lead to Aβ accumulation, tau hyperphosphorylation, and consequent neurodegeneration [one zero one,102].
