CC -!- FUNCTION: Plays an essential role in lymphocyte development by
CC negatively regulating the canonical Wnt signaling pathway (By
CC similarity). In association with UBAC2 and E3 ubiquitin-protein ligase
CC AMFR, promotes the ubiquitin-mediated degradation of CTNNB1 and Wnt
CC receptors FZD6 and LRP6 (By similarity). LMBR1L stabilizes the beta-
CC catenin destruction complex that is required for regulating CTNNB1
CC levels (By similarity). Acts as a LCN1 receptor and can mediate its
CC endocytosis (By similarity). {ECO:0000250|UniProtKB:Q6UX01,
CC ECO:0000250|UniProtKB:Q9D1E5}.
CC -!- SUBUNIT: Dimer (By similarity). Can also form higher oligomers (By
CC similarity). Interacts with LCN1; this interaction mediates the
CC endocytosis of LCN1 (By similarity). Interacts with UBAC2, FAF2, VCP,
CC AMFR, ZNRF3, CTNNB1, LRP6, GSK3A, GSK3B, FZD6, DVL2 and RNF43 (By
CC similarity). Interaction with LGB and SCGB1A1 is controversial (By
CC similarity). {ECO:0000250|UniProtKB:Q6UX01,
CC ECO:0000250|UniProtKB:Q9D1E5}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q6UX01};
CC Multi-pass membrane protein {ECO:0000255}. Endoplasmic reticulum
CC membrane {ECO:0000250|UniProtKB:Q6UX01}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the LIMR family. {ECO:0000305}.
