Supplementary information

LC3B also known as microtubule-associated protein 1 light chain 3 beta plays an important role in autophagy a process that maintains cellular homeostasis. The LC3B protein with a molecular weight of approximately 14 kDa undergoes lipidation to form LC3-II which associates with autophagosomal membranes. This protein expresses ubiquitously in various tissues including liver muscle and brain. Researchers often detect LC3B using techniques like LC3B western blot and LC3B immunofluorescence due to its function as a marker indicating autophagy levels.

Biological function summary

LC3B contributes significantly to the formation and maturation of autophagosomes. LC3B part of the autophagy-related protein complex binds to autophagic membranes. During this process LC3-I converts to LC3-II a lipid-phosphatidylethanolamine conjugate essential for autophagosome membrane expansion and closure. This mechanism helps remove damaged organelles and misfolded proteins from cells therefore contributing to cellular quality control.

Pathways

LC3B integrates into the autophagy pathway which is critical for cellular adaptive responses to stress. The mammalian target of rapamycin (mTOR) pathway regulates autophagy where mTOR inhibition activates LC3B promoting autophagosome formation. Moreover LC3B operates alongside other proteins like Beclin-1 and ULK1 facilitating the initiation and progression of autophagy under nutrient starvation conditions. These interactions highlight LC3's role in cellular energy balance and survival mechanisms.

LC3B connects with conditions such as cancer and neurodegenerative diseases. Altered autophagy levels mediated by LC3B often associate with tumorigenesis where its dysregulation can affect cancer progression. Furthermore LC3B also links to neurodegenerative diseases like Alzheimer's where impaired autophagy disrupts neuronal function. LC3B interacts with proteins such as p62/SQSTM1 which affects protein aggregate clearance a critical factor in neurodegenerative pathology.

Target data

Ubiquitin-like modifier involved in formation of autophagosomal vacuoles (autophagosomes) (PubMed : 20418806, PubMed : 23209295, PubMed : 28017329). Plays a role in mitophagy which contributes to regulate mitochondrial quantity and quality by eliminating the mitochondria to a basal level to fulfill cellular energy requirements and preventing excess ROS production (PubMed : 23209295, PubMed : 28017329). In response to cellular stress and upon mitochondria fission, binds C-18 ceramides and anchors autophagolysosomes to outer mitochondrial membranes to eliminate damaged mitochondria (PubMed : 22922758). While LC3s are involved in elongation of the phagophore membrane, the GABARAP/GATE-16 subfamily is essential for a later stage in autophagosome maturation (PubMed : 20418806, PubMed : 23209295, PubMed : 28017329). Promotes primary ciliogenesis by removing OFD1 from centriolar satellites via the autophagic pathway (PubMed : 24089205). Through its interaction with the reticulophagy receptor TEX264, participates in the remodeling of subdomains of the endoplasmic reticulum into autophagosomes upon nutrient stress, which then fuse with lysosomes for endoplasmic reticulum turnover (PubMed : 31006537, PubMed : 31006538). Upon nutrient stress, directly recruits cofactor JMY to the phagophore membrane surfaces and promotes JMY's actin nucleation activity and autophagosome biogenesis during autophagy (PubMed : 30420355).
