3 different light chains, LC1, LC2 and LC3, can associate with MAP1A and MAP1B proteins (By similarity). Interacts at microtubules with CABP1 (via EF-hands 1 and 2) but not with calmodulin (PubMed:15095872). Interacts with FYCO1 (via C-terminus) (PubMed:20100911, PubMed:24089205). Interacts with TP53INP1 and TP53INP2 (PubMed:22470510). Interacts with TBC1D25 (PubMed:21383079). Directly interacts with SQSTM1; this interaction leads to MAP1LC3B recruitment to inclusion bodies containing polyubiquitinated protein aggregates and to inclusion body degradation by autophagy (PubMed:17580304, PubMed:24089205, PubMed:24668264, PubMed:18524774). Interacts with ATG4B, MAPK15 and BNIP3 (PubMed:22948227, PubMed:23209295). Interacts with MAPB1, KEAP1, PCM1, OFD1, CEP131, and TECPR2 (PubMed:20562859, PubMed:24089205). Interacts with TBC1D5 (PubMed:22354992). Found in a complex with UBQLN1 and UBQLN2 (PubMed:20529957). Interacts with UBQLN4 (via STI1 1 and 2 domains). Interacts with UBQLN1 in the presence of UBQLN4 (PubMed:23459205). Interacts with ATG13 (PubMed:24290141). Interacts with RETREG2, RETREG1 and RETREG3 (PubMed:26040720). No interaction, or very weak, with WDFY3 (PubMed:24668264). Interacts with PLCL1; the interaction inhibits autophagosome formation (By similarity). Interacts with TRIM16 (PubMed:30143514). Interacts with CRY1 and PER2 (By similarity). Interacts with the reticulophagy receptor TEX264 (PubMed:31006538, PubMed:31006537). Membrane-bound form LC3-II interacts with PHB and PHB2; the interaction takes place upon Parkin-mediated mitochondrial damage (PubMed:28017329). Interacts with PJVK; the interaction is direct (By similarity). Interacts with KBTBD6 and KBTBD7; the interaction is direct (PubMed:25684205). Interacts with AMBRA1 (via LIR motif) (PubMed:25215947). Interacts with JMY; the interaction results in the activation of JYM's nucleation activity in the cytoplasm (PubMed:30420355). Interacts with MOAP1 (via LIR motif) (PubMed:33783314). (Microbial infection) Interacts with Hantaan hantavirus glycoprotein N; this interaction contributes to the virus-induced degradation of mitochondria by autophagy, which leads to degradation of host MAVS and inhibition of type I interferon (IFN) responses. (Microbial infection) Interacts with Hantaan hantavirus nucleoprotein; this interaction prevents the breakdown of the viral glycoprotein N by virus-triggered autophagy.
