Monomer, homodimer. Can form heterodimers with other COMM domain-containing proteins but only certain combinations may exist in vivo (PubMed:23563313). Interacts (via COMM domain) with COMMD2, COMMD3, COMMD4, COMMD5, COMMD6, COMMD7, COMMD8 and COMMD10 (via COMM domain). Identified in a complex with an E3 ubiquitin ligase complex composed of TCEB1/elongin C, CUL2, SOCS1 and RBX1; in the complex interacts directly with SOCS1 and CUL2. Interacts directly with ATP7B (via the N-terminal region). Interacts with CCS, CDKN2A, RELA, REL, RELB, NFKB1/p105, NFKB2/p100, NFKBIB, SCNN1D, SCNN1B, CFTR, CLU, SGK1, AKT1, CUL1, CUL2, CUL3, CUL4A, CUL4B, CUL5, CUL7, HIF1A. Identified in a complex with NF-kappa-B. Interacts directly with SLC12A2. Interacts with CCDC22 and CCDC93; proposed to be a component of the CCC (COMMD/CCDC22/CCDC93) complex which contains at least COMMD1 (and possibly other COMM domain-containing proteins), CCDC22, CCDC93 (PubMed:25355947, PubMed:28892079). Interacts with VPS35L; the interaction associates CCC complex with retriever complex (PubMed:28892079, PubMed:25355947). Interacts with ATP7A (PubMed:21667063). Interacts with FAM107A; this interaction stabilizes COMMD1 in the nucleus (PubMed:28604741).
